Ive had one of the cheapy single burner ones for a while. I use it a fair bit. The only problem i find is when the butane cans get down to 1/3 they lose pressure so the flame wont go as high. Other than that they are awesome and they cans are cheap. I get the cans from Kmart- around $18 for 4 or 5 pack. (and $20 for the burner with a can or two thrown in)
Can you remove the hot plate on that one?
