The Jetstream, currently by DiveRite, or Poseidon Cyklons (avail. used cheap).
That said, the Mk17/G250 is a great rig.

Good luck buying your LAST regulator. LOL. I say that everytime I buy anything to do with diving, hunting, fishing, or golf.

You might want to consider the Zeagle Flathead VI, which is a "close out" item now since it was replaced by the Flathead 7 this year.
Buy The ZX Flathead-VI CLOSEOUT scuba diving gear at Zeagle Express
Parts should be available for a long time, and are inexpensive. The service manual is available online. I've bought two of these, heavily used, rebuilt them, and they are fine regulators. Rebuild is very simple, and any tech should be able to do it.
Better yet, learn to do it yourself. VERY easy with this particular regulator. Then you'll have true worldwide, 24/7 service availabilty
Best wishes.

There are great deals on used regs. You can probably find a good MK10 or MK20/25 with a G250 or D400 2nd stage for good price. I bought a practically like-new MK10/D300 for $84 and it's about my favorite reg. If you're looking for a sealed reg (very very cold water use) the MK17 has been around long enough, otherwise go for one of the SP balanced piston 1st stages. They're great performing, parts and service are everywhere, and they can usually tolerate several years between rebuilds IF it's done right and IF you rinse/store them well. IMO the MK20/25 will last longer between rebuilds due to the rounded piston edge and nice new seat materials.
The old style G250 is what the G250V was based on, and there are plenty of those around in great condition. I like the D series a little better, but since you said "last reg" you might want to stick with the G250 as its poppet and seat are currently in use and will doubtlessly be supported for another few decades.

Why don't you order the environment kit for you cressi? that is like a 50 dollar part, I dove mine cressi after adding the kit in 5 degree celsius and it had no problems. It may give you some time to get the money together to get the thousand dollar reg everyone seem to be suggesting. Or get like a oceanic Delta 4, it will be sub 600 with everything. jmtc.
Also you can order a din conversion kit, for about 60 bucks from cressi.

Mk17/G250V is a good performer (also in cold water), quite robust, and very good value for money. I like the G250V, with its full metal barrel, much more than the S600, whose barrel is kind of plastic. You may be able to buy a G250V separately as an octo (it depends upon the country) but it may not be a bargain because the price of a combo Mk17/G250V is normally quite less than the price of the Mk17 and the G250V bought separately. You may then find more attractive to buy two combos and keep one first stage as a spare (this applies to many brands). In many places, two first stages (on a twinset or a H or Y valve) are considered mandatory for cold water diving, anyway ; and rightly so with 30° Fahrenheit water !
Nonetheless, I doubt the G250V will last 20 or 30 years (unless you leave it on a shelf as ornament) because of the plastic casing. That applies to most 2nd stages, unfortunately, unless you opt for a metal one.
Scared Silly says it all about DIN and yoke. Just note that, if you don't use a DIN-to-yoke adapter, then to remove the yoke and put the DIN kit (or the opposite) you normally need a dynamometric wrench (to put the right torque) and some care to not ruin the kit ; this operation is easy and takes 5 mn for a tech with the proper tools, but not for anybody.
Mares MR22T Abyss is also very good value for money, good reg for cold water (even without environmental kit) and very durable thanks to the metal 2nd stage. You can buy the same 2nd (Abyss) separately as an octo. IMHO the Abyss is much more reliable than the Mares Proton.
For the ability to have your reg serviced everywhere in the world, you may check where you plan to dive and if there is a distributor there - for example, Scubapro parts and/or service for "high-end" regs like Mk17 or G250V are not so easy to find (yet) in some places in Egypt. But you may take the parts with you. Check also if service is complicated and/or needs special tools.
Anyway there are many other good regs around. Good luck with your search !

I like the Posedion XSTREAM, lifetime warrenty,depths of 640' tested.So far no problem.(getting it serviced takes a week from my local diveshop.)
You might want to opt for the Poseidon Duration though, since its also Nitrox compatible, which makes it even more future proof, the depth rate is the same as for the Xtreme 90

I'm thinking about doing exactly this. Wanted some validation that it's not a crazy idea.
Spending 110 bucks to add a enviromenat kit and din kit vs. spending 600 for a new reg. Do not seem crazy to me. If you want a new reg, that is a different story. Because we all love our shinny new toys.
But if you have any question can always contact cressi directly. They have always responded to me quickly. I sent them a question about nitrox, and they got back to me in couple of days. They told me that the ellipse is nitrox compatible up to 40%, it is design to meet ec regulations.
