Been using the Pocket Rocket for a quite a few years and I have nothing but great things to say about it. I've never had problems finding fuel but I usually bring my supply of fuel with me (no airlines however).

The other one that I think is great is the jet boil all in one. Its so simple and all right there. But except for boiling water and dehydrated meals, it does not have alot of uses. If I knew i was eating all dehydrated, the jetboil would be my choice.
