I diagree with some of the comments on the jetboil, its stands up easily with tha aditio of the plastic tripod, it will cook easily any manner of food due to the panstand attachment, which with any pan will be able to rustle up any meal, as for gas canisters, the small size that fits in the in the jetboil along with pan stand and tripod has happily lasted me for weeks, the addition of a lrge gas can will see you and four peoples worth of cooking for a couple of weeks, so unless you going to get lost for a month i would reccomend it, There is plentifull supply in all countries.
If you cant operate it due to cold hands then you are not looking after yourself properly in the field.
