First, to answer the question, I use my Jetboil more than anything else; only four components, fast and efficient.
However, lately I have been learning and experimenting with TrailDesigns Caldera cones.. using these has been the only way for me to make alcohol cooking almost as hassle-free and convenient as my jetboil. Caldera cones combine the windscreen and pot support into one unit. The base of the cone is MUCH more stable than a little wire pot holder, and the windscreen envelops the pot, unlike aluminum foil. Also, it just looks a little more elegant than chicken wire and wrinkled aluminum foil. One good thing about the cones is that they can be used with multiple fuel sources, while maintaining the wind-resistance.
This photo shows some of the setups Ive tried.. when using a canister stove, the caldera friction fits to the pot and 'hovers' a few inches off the ground.. The cansiter stays cool, and the burner stays protected from the wind.
Cat, to answer your question, Snowpeak says the warrantee will be voided by using any other fuel, but I mix and match whichever canisters are cheapest with no fuel-related problems.
