I highly recommend an Esbit tablet stove- I have an MSR whisperlight but don't use it b/c it and the fuel is too heavy/bulky compared to the Esbit and some tablets or fire sticks. Granted, most of the 'cooking' I do is making coffee for myself, since i mostly eat stuff you don't have to cook on tour. But my Esbit has been with me on a 5000+ mile trip and served me well.
Anyway the Esbit stove is cheap, durable, and you can find fuel tablets at almost any outdoor store, and if you can't find those you can usually find fire sticks, and if you can't find those you can improvise. It's a highly versatile little contraption that you can buy for about 15 bucks.
