You just can't justify tanks, financially... Around here, the difference in cost between renting a tank full of air and paying for an air fill is about $3. A new HP 100 costs about $360 including tax and to be useful, I need at least 2 per diver (4 of us!). So we're looking at $720/$6 (for a pair) or about $120 dive days to pay back. That's kind of a long time at 5 or 6 days per year.
Yes, Al 80s pay back in about 50 to 60 dives... That would be about 10 years, give or take.
You can't justify them on the basis of convenience because it still takes 2 trips to the shop to get them filled (unless you wait around and then you get them hot).
When we're staying out of town for a two day trip, we can only use my tanks for the first day because I won't have them filled just anywhere. They are O2 cleaned and I want them to stay that way. So, we wind up renting tanks anyway. Might just as well rent them all...
The only possible way to justify buying tanks is the convenience of taking them out of the garage and loading them in the SUV. Diving at a moment's notice. And that's why we have 14 tanks of various sizes.
