I've got 2 Klose cookers (one mobile unit, one small BYC) both with propane assist. It's ok. If I had to do it again, I wouldn't. I can start a fire just as well with a chimney full of charcoal, so all that equipment saves me ... 10 minutes per cook? Maybe. In the offsets I've got, I can just open wide the door to the firebox and it's plenty to ignite new logs or coals.
