The coleman suitcase stoves run on petrol or coleman and are built to last. Woodsmoke do all their cooking on them at their courses. I find they run really well on petrol but stink and give off nasty fumes so wouldn't be good in a tent, and for some reason if I run mine on true Coleman fuel (about the same price as a fine wine) they guzzle fuel at an alarming rate.[/url]
There are alternative fuels as discussed on this thread. Aspen smells quite nice for a petrol, and does give off quite so many nasty fumes.

Stockists can be a bit hit or miss, but Axel from Aspen was making sure it was updated.
