If you've got a little time, you may want to wait for jetboil's new system to come out in march. It's got a bigger pot so you can cook pretty much whatever you want (it includes the stabilizer, etc.--if you wanted the other jetboil cup to add to it, you can pick those up pretty cheap on ebay).

I have a regular jetboil but haven't used it a whole bunch yet. It does seem to conserve fuel in that it takes much less time to get water to boil--faster than a microwave or stove or anything else I've ever used. I'm really excited about using recipies from
http://freezerbagcooking.com and not having anything but a spoon to clean up. You make dry-ingredient meals ahead of time, pour in boiling water in camp, and have a hot meal in about 5 min. Pretty nifty system to use with something like a jetboil.
