Coleman PerfectFlow 2-Burner Propane Stove

Used one several summers in Alaska. It worked well but carting around extra and empty fuel cartridges is the price that you have to pay for propane. Fuel use seemed pretty good, we ended up with extra cartridges each year. 

Doesn't seem to burn quite as hot on high heat as the white gas systems.  If my white gas Coleman dual burned needed to be replaced I would consider this stove as an option.
