I agree the dragonfly is a great and relatively inexpensive stove. I've used it in temps exceeding -30 in Argentina. One thing to look out for, though, is the pump action on these puppies can wear over time and there's a little rubber grommet that, when frozen, can let pressure leak out the pump. If that happens, pop the pump open, dab a healthy dose of chapstick around the ring, and smoosh it back in. Fixed mine for a whole nuther season. =)
