Have to say that the Coleman Exponent F1 is a great little stove, weighs 2.7oz, boils a litre of water in 3 minutes and simmers quite well. Packs super small, fits in the small Evernew pot with the canister and the whole rig weighs in at just over 18oz.
I have a Coleman Exponent multi-fuel stove. Its a bit heavier than some, but always got the job done. I actually just sent mine back to Coleman for a rebuild. Wasn't holding pressure anymore. Could have done it myself, but for as old as it was, it should get a once-over by someone who knows more about them than I.
