In reply to James Monypenny:
I've used both, each has their advantages. Best is a fuel stove that also has the fitting to accept canisters (eg. Primus Multifuel etc). Last time I did this I ended up using the canisters more than the fuel, it's just easier, cleaner.
I know burning petrol is dearly loved here on UKC but fuel stoves burn best with white gas and that's hard/impossible to get in the 3rd world. Kerosene is possible but is often dirty so you have unreliable and messy use.
Canisters are everywhere in Kathmandu, easy to get. Not been to India. Jeboils are easy to use at altitude, simple and light. Just keep the canister warm and take a lighter or matches as the Piezo usually dies above 5000m.
