Ford vs. Chevy: I'm the only one who's right!
I've used an older Peak1 single burner, an MSR Whisperlite International, and now an MSR Dragonfly. I see the ease of the cartridge stoves, but they have some drawbacks as well, and I've decided they're not for me. Drawbacks include fuel cost, availability, waste of empty canisters, having to tote two canisters as one is always "almost" empty, etc.
I was on a trip with a buddy, using my Peak1. My water was on the stove, heating. My buddy came in, assembled and lit his Whisperlite, and had boiling water before I did!:laugh
I bought a Whisperlite. I think it burns hotter than a burner on my gas range. A backpacker in the store at the time recommended the Dragonfly, as it simmers better, but I was mostly into boiling water and heating canned crap at that time. A couple summers later, a bunch of us were making soft tacos for the whole crew on a trip. My buddy warped my frying pan, the Whisperlite was so hot!:doh In my experience, the Whisperlite doesn't simmer very well...:laugh
Enter the Dragonfly. It simmers better than the Whisperlite, and I'm very happy...:whistle
I like the multi-fuel stoves, though I usually burn white gas (read:Coleman fuel). If I bring a quart bottle, it will last through [U]many[/U] days of regular cooking, or a week of heat 'n eat type meals. It's easy to "top off" before leaving, so I always leave with a "full tank" for my stove. White gas is pretty much universally available in the US, including small town gas stations, hardware stores, etc. Not always true with the proprietary fuel cartridges. You can sometimes find quart bottles, as well. I've never found the setup/pumping to take more than a couple of minutes, and don't find it objectionable. The MSR stoves are also easily rebuildable at home, though I've never had to do so yet.
If you take along a fuel bottle of gasoline in your pannier, you also have an extra "reserve" in case of running out of gas. A quart of gas = a lot of pushing!:p
FYI, the boys at Thrifty Outfitters in Minneapolis used to advocate using a touch of liquid Gumout in the fuel for the stove- maybe a capful to a bottle of fuel. They claimed it helped keep the fuel lines, etc., clean. [url]http://www.thriftyoutfitters.com/[/url]
