This would be used for weekend trips, three seasons. These are much easier and safer to use than a white-gas stove. The tradeoff is that canister-fuel stoves have a considerably higher fuel cost. But I still think the convenience and safety is worth it. The Gaz is a proven, reliable design that's compact and burns well.
Fuel is very easy to find.
Fuel costs seem slightly lower for the X-Pert and it burns about 20 percent hotter, meaning your hungry Scouts will chow down sooner. True, the initial cost of the X-Pert is higher, but I think it will be a better investment. No matter what stove you decide on, I think it's important for a responsible adult to be close at hand. Though the Turbo and X-Pert are what I would consider safe stoves, they both use highly flammable fuel and burn at high temperatures. Accidents can happen.
