We had a Wallas diesel cooker and stove, took it out and replaced it with a propane model! The Wallas stove took a while to heat up, if you turned it off you couldn't restart it until after it had gone through a cool-down cycle for ten minutes (fancy a coffee? Oh, sorry, I can't begin to boil the kettle again for ten minutes...), also the entire ceramic stove top heated up when turned on rather than individual rings which gave off a lot of residual heat, perfect for the tropics
.
Sadly it wasn't particularly reliable either - too many circuit boards and soenoids and pumps for my liking - keep it simple and squirt propane through a nozzle, I can fix that when it goes wrong!
