I'm' with the folks on the other forum - why? the fuel won't burn as well as the canisters of iso pro you get to work with the Lindl valve stoves we see on shelves today. Unless you have a garage full of those canisters it seems like a lot of expense for not a lot of gain.
Although, the adapter would be a good alternative if you cant find ISO-butane/propane mixes. I have a bunch of propane canisters (about 6-7 for stoves and lanterns). Yes, its heavy and a space-hog, but not for car camping or general picnics where there isn't any feasible public bbq sets.
