I have been using Primus stoves for a while now and I cannot tell you how happy I have been with mine. I have a Yellowstone Classic model stove with a piezo lighter for it. They make a lantern that attaches to the same fuel canisters, and I have heard good things about it. I've seen one in use once, but I didn't have another lantern to compare the brightness to. The benefit of this design is that it is a steel mesh lantern that doesn't need to be replaced, AND you get to carry one type of canister for your fuel. If you plan on doing any backpacking or want to travel light, the Primus stoves (and it looks like that lantern) would be a good choice.
