MSR Dragonfly, offers use of unleaded pump gas, (or Kero)

My because: Fuel for cars are everywhere, alcohol for stoves less so..
butane cartridges even less common..

I've refilled my fuel bottle at petrol stations for 25p .

and it uses 2 valves , 1 on the tank/ fuel bottle, that is the shut off,
and another on the Burner.. so can be full roaring boil or throttled down to a simmer..

you can cook on it as opposed to just boil, etc, with high heat.
