I own an O2 kit with an MTV-100 that lives in my vehicle 24/7. The odds of using it while diving are negligible because it has limited capacity and is only particularly useful IMO for resuscitating a victim in conjunction with an AED since the MTV-100 lets you give rescue breaths.
For diving use I carry a RescuEAN and an AL40 or 80 full of O2.
 
No, but I also bring a rescuEAN and an al40 of O2 when diving in FL. I don't bring it on international trips.

Interesting, I hadn't heard of a rescuEAN yet. You combine that with an O2 source to give gas to an conscious or unconscious diver?

 
Yeah, that's the idea. I've never actually used it other than figuring out how it worked. I already had the O2 bottle for accelerated deco, and the device was fairly inexpensive for a little extra piece of mind. Also, no trouble getting a deco bottle filled at any shop that supplies O2.

Come to think of it, I need to service it and replace all the soft parts I'm sure.
 
I took an O2 provider course which makes things easier to get oxygen without a prescription. Then put together a kit piece by piece, much cheaper this way.
My take is, there is always a risk of a dcs hit. The best course of action is to get on O2 and call DAN. So I enabled my self to have O2 available on every dive I make cause you never know when you’re gonna suffer an undeserved hit.
 
Found a newish "E" bottle and regulator on Craigslist from someone who moved to a concentrator, filled at my LDS, masks/tubing from Amazon, packed in an EMS bag off eBay. < $200 all in.

This is what I did as well. I found a guy selling E cylinders, full but out of hydro, for $10 apiece on Craigslist. I verified it was O2 with the analyzer at the shop. I picked up a 25l reg for $10 on Ebay and had a few non-rebreather masks laying around. The entire setup cost me around $25-30. This set up is sufficient for 99% of the diving most people do.

The DAN kit is totally overkill for most people. It is better used as a training unit or for a commercial (e.g. boat) than for most practical purposes IMO.
 
I do not have one, but I'm taking an O2 provider course later this week. I intend to ask the instructor his views on the DAN kit, the DGX kit, and homebrew solutions. Also will ask what it's like trying to get fills locally -- like is the best place a dive shop, a gas/welding supply place, or somewhere else.

For those who have them, it seems like D and E cylinders are common, and that the expected use-case is 1-2 divers breathing at the surface for 30-60 minutes. Do I have that about right?

Depending on who the provider kit is for and how well versed the instructor is *most are not*, he'll say to just buy the DAN kit.
Here's the deal. Nothing in the DAN kit is unique to DAN. You are paying for the convenience of them putting the kit together for you.
Closest comparison is these two products with a Jumbo D/~22cf tank

In both you get a Jumbo D cylinder with pin index valve which I personally believe is utterly useless in most applications. They are rated at ~40 minutes at 15lpm which is about 0.5cfm and what a diver is going to be breathing just hanging out at the surface. This is NOT enough to get you to a hyperbaric chamber from a shore dive area, it is not enough to keep you on O2 until you get hooked up when at the hyperbaric chamber, and is nowhere near enough to get you to a chamber from a boat. These bottles are enough to sort you out while giving rescue breaths to a non-breathing patient, but are just enough to give you a false sense of security IMO.

Differences
With the DAN pack you get multiple masks, with DGX you get one but these are cheap so not a big difference. If you intend to do rescue breaths with the DGX kit you will need to purchase a bag valve mask and know how to use it *possible to do with one person, but very annoying especially compared to the MTV-100*
Pelican case vs cheap sleeve-Pelican not critical IMO unless you are storing this on a boat or in your vehicle 24/7
Regulator: DGX uses a standard el-cheapo pin index regulator. Nothing special about it, easily replaceable. The DAN regulator includes a DISS port which allows you to use demand valves *more efficient if patient is breathing on their own, do NOT use for rescue breaths*, or an MTV-100 *very expensive but functions like a demand valve if patient is breathing and can safely be used for rescue breaths instead of a bag valve mask*
DGX includes a Pulseox-nifty to have but not really a diagnostic function for someone with DCS. Probably more useful for pulse than ox but they're $25 so easy to add.

Basically between those two you have to evaluate the odds of you needing to resuscitate a victim. If you think that risk is negligible and are comfortable using a BVM, then get the DGX and save a couple hundred bucks. If you think the odds of you having to give rescue breaths are not negligible, then you will not be able to piece together a kit with an MTV-100 for much less than the DAN kit and I would go with the DAN kit.
If you are considering the DGX kit and don't mind buying used and/or have access to medical O2 cylinders, then the O2 regulator is $25, a backpack case for the system designed for a jumbo D for $40 ish, and a 3-pack of Oxygen masks for $15. $80+bottle, or $100+bottle if you get a pulseox.

My personal O2 bottles use a Western Enterprises Oxytote NG valve/regulator on them that allows me to fill from a standard CGA540 valve *same as the big T bottles*, and since it is all-in-one with a DISS port it's much easier than dealing with multiple cylinders and having to move regulators around but it is not the "cheap" solution when compared to buying $10 medical bottles on Facebook Marketplace and grabbing a $25 regulator from Amazon *I think the valve/regulator is about $100 or at least it was the last time I bought some*.

All that said, and I've argued this before, for divers there is NO reason to own an emergency medical kit. They are a PITA to get filled, they are inadequate in terms of size, and are single use items. A better solution, albeit a bit more expensive, but MUCH more versatile is to get a deco bottle set up and use a RescuEAN.
AL40-$200 and holds ~30cf of gas at 2200psi vs 22cf of gas in a Jumbo D. Holds 40 if you have a shop with a booster for O2.
Stage bottle regulator+drysuit inflator hose-$400 and can serve double duty as a pony regulator if you believe in such things, act as an actual deco bottle, or at least as a spare to your current regulator in case something goes sideways but either way it's a more versatile system.
RescuEAN- ~$150 for the advanced kit with the bag valve mask and other non-rebreather masks, pod itself is ~$90. Can be used with ANY bottle that has an inflator hose on it so even if you run out of O2, you can at least put them on nitrox if you have that which is better than nothing.
Whole system brand new is probably $800 ish vs $300/$600, but your emergency O2 only is $150 max and the rest has multiple uses for a diver. That to me is money well spent.
 
For those without a prescription, ask your industrial gas supplier if they'll fill a medical bottle with aviators. That's the case with my gas supplier if you lack the "credentials", They'll gladly fill medical bottles with ABO no questions asked.
 
I bought one from a guy who taught my First Responder class a few years ago for $ 200. I never used it even one time ( a good thing !) and my diving was becoming much less frequent - so - I sold it for $ 250 to a guy who had thought he could use it for his DM classes he was just enrolled in. The green tank needed hydro many years ago - but he didn't care. This was the 19 cf bottle in the DAN green pelican and man I should have sold it for $ 400 based on the insane prices DAN now charges for this kit. It's like $ 500 + now on their website.
