FYI…just noticed people selling Coleman Powermax stoves and fuel canisters on Ebay for really high prices. Fuel bottles that used to cost around $5 are now going for $30 or even more. So if you have some fuel bottles from years ago, now is your chance to make a killing. I saw a stove plus three fuel bottles going for $125.
Coleman produced an adapter that allowed you to use normal Isobutane cartridges with the Powermax line of stoves, I recall it didn’t work as well but it worked. I think it was liquid feed.
I actually have two single-burner stoves, one double-burner stove, and a box of fuel cartridges. I was saving them for winter camping, but now I’m not so sure…
