Whatever your choice, don't scrimp. A cheap stove may break down on the trail, ruining your entire trip. Ease of cleaning and repair, Ease of use, Availability of fuel, and cost. When shopping for a stove, keep these things in mind, ask a lot of questions, and don't buy the first stove you see. Shop around and compare.
White gas is an efficient, clean burning fuel.
It also has a high heat output. White gas is good for summer or winter but not as good at high altitude. I own an MSR Whisperlite International. It's a few years old and still going strong. The Whisperlite International is a multi-fuel stove.
