I've had the Whisperlite Internationale for probably 8 years... runs on white gas or gasoline with one jet, diesel or kero (and allegedly jet fuel) with the other that comes in the package. Gets pretty dirty on diesel and doesn't like wind without using the aluminum shields that come with it, but it's simple and reliable. Fuel lasts for freaking ever; I cooked two meals a day for 3-5 people for 3 days and barely made a dent in my quart of white gas. The hardest part getting it going in the cold is getting the lighter or match to stay lit--the stove works fine, at least on white gas or gasoline. Essentially it's a lighter, cheaper version of the Dragonfly. The Dragonfly definitely has a better flame control for low heat, though it can be done on the Whisperlite as well. That Optimus Svea looks pretty awesome. No priming would be great.
