I bought the Iwatani and went to the Korean grocery right by my house. Thanks for the tip. Got 4 huge cans of butane for 6 bucks. Amazon wanted more than twice that(more than triple if you want the Iwatani brand canisters). Anyway, this thing kicks ass. I wish I had one of these when I was a pyromaniac kid! Ok...maybe not.I have that exact one, it's awesome, dont' forget to pick up

if you live near an asian grocer, the butane will be WAY cheaper, just ask for the butane for "hot pots"
But one can will last you a LONG time, I'm still on my first can, probably went through a lot of cows and fish already with it.
