I have lugged around my MSR whisper light most of the time and played around with esbit cubes, alcohol stoves and even just using a cheap fold flat wood burner.

But lately I really like my jetboil its an all in one deal. I picked up the french press screen for it and now I have great REAL COFFEE with a minimal weight gain.

I know that it is far from an ultralight stove but I consider it almost a luxury after fiddling with other ultralight options.
