If multi-fuel is a requirement then look at Optimus Nova or MSR Dragonfly. I have both, personally I like the Optimus better but most backpackers prefer the Dragonfly.

For real KISS, look at a beer can stove.

Consider putting one in your BOB. My stove, 500cc of fuel, a 500cc Ti cup, and a sheet of heavy aluminum foil (wind screen/heat reflector) packs down to less than 1L in volume and is very light weight.
