In the collector world, at least, stoves aren't worth much. Lots of people get them for free from people cleaning out their garages. I paid $5 for a 413 in great condition last year.

In terms of using them while camping, I'll have to admit that the propane stoves are much easier to use. As others have said, though, fine adjustment of the flame is not easy and on some models it's downright impossible. I'm not sure where modern Coleman propane stoves are made, I'm assuming they're all made in the same Chinese factory these days.

We have a camp chef propane we use when camping. I'd like to start using white gas but between the hassle and potential mess of carrying fuel and the more difficult operation (requiring pumping up the tank) I don't think I'd be able to sell the wife on the marginal benefits of white gas vs. propane.
