@Satrekker... you broke the rules, didn't you?
These things are not timid. I kept my two under lights in a public shop and I just loaded up 27 of them for a dive trip.@Satrekker... you broke the rules, didn't you?
I've recently been thinking of getting a pair of own sidemount cylinders but am not sure whether it makes sense. My local shop charges $20 to rent one, so each outing ends up costing me $40. They're Nitrox filled and I don't have to worry about maintenance and storage.
Aluminum tanks with valves would cost about $700 for the pair plus $15 each for the initial fill. That's a total of $730 to own. Within this $730, I'd get 18 rentals of filled tanks ($730/$40). If we then multiply this 18 by the $30 it would cost to fill my own tanks for this many dives, we get $548. Divide this by $40 again and we get another 14 dives. If we keep going until it zeros out, we arrive at 70 dives. If the math is correct, that's 70 dives until we get any ROI.
Does it then make sense to own tanks? If you're a proud owner, what benefits (cost-saving or other) do you get that you otherwise would not? Thanks in advance for feedback.
I am not sure 2x AL80 cost $700. I think it is more like $350-$400 including valves. If you are OK with used, they can be had for significantly less.
If you are diving air or nitrox in single AL80 (or side mount AL80 for that matter), you are only gaining convenience by owning the same tanks. But if you don't have place to store, I probably won't bother owning. That is one advantage of side mount.
Beware tank creep. I started with 2 steel HP 100s but needed a 3rd for 3 tank spearfishing and shark dives. Then one day, my local captain called a few hours after I just finished diving with him and said that he had a spot open for the next morning. Well, there was not enough time to get my tanks refilled, so I only had one of 3 ready to go. Now, I've got 4 HP 100's. Oh yeah, now that I'm really getting into spearfishing, I've got my first HP 120, and I'm sure it's brother isn't far behind. LOL

@W W Meixner - notice the plural in valves.... We are all quite sure it was meant to be for two.... agreed, $350 - $400 is nuts for a single aluminum, and almost too much for steel (even in Canadian - lol)...
YMMV
I’ve got so many tanks now I’m doing a VIP class in a few weeks.
