If you want two burners I'd go with an external metal attach and hard metal propane container. For a single burner though, I go with what OTHERS recommend - the butane canister model that slips into the unit (after a panel is lifted up), lever is activated, spark and then instant flame. The units are very light weight, dependable and have sure fire heat. The units though do NOT have side panels that deflect wind or dust and in heavy weather need to be shielded. I have two different brand models, one with fancy red paint and the other black - my guess is that both came from the same manufacturing region in China though.
