don't go for a gas stove - they are no good, you can't use em on uneven surfaces or when it's very windy, and the gas is expensive

trangias are a bit bulky, but they are light, and use the widely available and cheap drink of vagrants - meths (a shop in London was recently prosecuted for serving bottles straight out of the fridge)

I really hate gas stoves - have lost a few nice dinners due to their instability
