I'm still using my Powermax canister fueled Stoves -
Exponent eXtreme single burner - 14,000 BTU, 11-ozs
I still have several of the Xpert and Xtreme stoves. Not quite a life-time supply of canisters, but I have the Coleman adapters for each stove to use the standard canisters. They've held up on 6 Philmont treks and many Troop backpack trips. I like them.
I also have an MSR Whisperjet and a couple of alcohol stoves that get used on my own trips.
