MSR XGK (firsthand experience) and relatives. Note that the MSR XGK is a noisy bugger (Primus type roarer burner) and its forte is rapidly boiling water, not simmering.

Coleman Peak I varient (first hand experience). Must pre-heat, which is usually not the case with naptha type fuels. Once the generator is hot, cooking of all sorts is feasible.

The heavier fuels like JP and kerosene are a bit more involved than naptha fuels and in my experience ALWAYS gave me a stove redolent with residual fuel aromas - so external carry is my strong suggestion, rather than internal carry.

The XGK rapidly converts back and forth on fuels; a bit more effort required with the Coleman to switch, but neither is difficult. I think some of the other MSR stoves may be convertable as well, but I have not kept up to speed on them.

HTH,
