I'm going to get some kind of wood burning stove before my next spring trip, whenever that is :(
 I'll bring my trusty Peak 1 multi-fuel for a quick start in the morning, and use the Wood-Burner for the evening meal, and starting the campfire. I figure the trade-off from bringing less Coleman fuel and the weight of the Wood-Burner, will be about even.
 Another thing I'm looking at, is that with my dry-fly tarp/tent set-up, that little Wood-Burner would allow me to use it as a miniature heating stove, if I rig some kind of spark arrestor for it.
 I'm hoping someone that has either the Zip Stove or Wood Gas stove will way in on the differences IF there is any?
 Worse case scenario, I'll order BOTH and send one back.
 PS, Mad Mat is dead on about the liquid gasoline comment!
When I was a young buck , I worked with my Dad, we installed gas tanks/pumps and hoists in Service stations. Some was new work, most were additions, so we were around gasoline and vapors. My Dad showed me the real danger with a little "FARMER" experiment. He filled a metal bucket with gasoline, and proceeded to light a match, blow it out and threw it in the bucket :o
Too my amazement, the match went out! He then emptied the bucket into a bulk tank, and repeated the experiment. The bang and flash from the fumes scared the hell out of me, and made me realize what was the real danger was when working around or with gasoline ;)
