Coleman stoves may not be the lightest or the most technologically up-to-date camping stoves out there, but they are solidly built and if you take good care of them, can last for years and years.
The Exponent Duel Fuel stove is quite simple and offers the benefit of carrying its own fuel – especially on shorter trips when you don't want to have to carry an extra fuel bottle or canister. The stove gets its name from the fact that it can run on either coleman fuel (white gas) or unleaded gas. This is handy when you're in an area where white gas isn't easily available and you can't bring it with you. Performance differs slightly between the two fuels – with white gas burning more cleanly and slightly warmer, but either one will work quite well in the stove and should satisfy most people.
