Great StoveReview by Merlin
I always pack this stove when bike camping. It is a bit heavy and not at all good for backpacking, but on the bike I have no complaints. It's built like stoves should be built but rarely are any more. Fully rebuildable and a single tank will last an average week of camping, given that you use it twice a day to boil water or cook your meals. If you run out of fuel, siphon your bike and keep on cooking. (Posted on 10/13/12)

Over the years I’ve used several different stoves. First was a Svea 123 (#4146). Used probably ten years, and still have, all ready to go, inside an old Sigg Tourister cook kit. But to prime aSvea one must pre-heat the burner by spilling a little fuel into it’s burner cup and lighting it. When it’s just warm enough you crack open the jet for a self-sustaining (and loudish) flame.

It was replaced by a Coleman Peak 1 which was configured similarly but had a priming pump so it was easier to pressurize and light. Unfortunately, this model was discontinued a few years ago. The closest comparable stove available now is the Optimus Multi-Fuel (#4145).

For the last ten years I've been trying to like stoves with the removable tanks but can't quite get there. I’ve used several models and brands. They are excellent for some applications, but the extra step of connecting the tank to the burner has sometimes been a problem because I fumble and get gasoline on my hands, which is the last thing you want when you are hungry and about to be handling food.

Gas canister stoves are convenient, lightweight and clean, with replacement canisters widely available. We sell two good ones, but I still like being able to siphon fuel from my bike right into a stove when needed. A quick-disconnect to the fuel line makes refilling stoves easier. We also sell these. (#4197 and #4128.)
