I've never heard of this either, but I agree with the cautions that others posted. Tank "for life" is not your life, it's the shop's life. You shouldn't think of this as owning a tank. What you're doing is paying for a lifetime rental. If the shop keeps the tank, you have to expect you will not get it if they close. But you also won't be paying for fills, VIP or hydro. I really have no idea what a tank rents for, but divide your initial cost by the daily rental cost and that's your payback period. Sounds like a decent plan to me if all you ever do is dive air with enough notice to pick up the tank in advance.
