I have a Primus butane/propane stove and it works very well at temperatures above freezing and non-windy environments. It would probably benefit from the use of a simple heat exchanger, maybe homemade. The stove itself is very light and small. The canisters take up the majority of the space and you have to be careful about tipping the whole thing over.
