Beck I can tell you about one crappy stove, check out the Optimus Nova (which got all kinds of backpackers' awards and shit). Not long ago a Swedish expedition to Mustagh Ata was sponsored by Optimus and they brought several Novas to use on the mountain.
One minor problem though - the stove does not function at all above 4000 m.
So they got like totally pissed, dumped the fuckers and went straight down and bought some old LPG stoves.
I have the Whisperlite Intl and it runs smoothly as a baby. Used it with kerosene, oil-blended gas for small boat engines, all kinds of stuff from the paint shop and so on. No problem.
