I agree with JonB. I'd never cooked on a kamado either before getting my KK, although I had been around two cooks on a pos Kamado (fortunately an early one, so not in and of itself a pos) owned by a friend. The KKs are actually much easier to cook on, and with much better results, than my previous charcoal smokers and grills, as well as my large gas grill, all of which have now either been given away or decommissioned in favor of the KKs.
Fair warning, one KK is terrific; two is much more better.
