Got it for $10 at salvage yard That's a great way to go, I paid $500 for an own your own bottle, the one advantage being its a swap bottle so I never have to cert it. But its about $140 to swap for a full one from memory. I rented one off BOC for years, but cringed every month when I had to pay rental on two bottles.
