The biggest single step up in my smoking was the purchase of my egg. The ceramic cookers, IMO, take it to a new level. They provide a moist environment (highly efficient, little air passing through the cooker), extremely stable temps for long periods (think, I can sleep at night) and repeatable results. Costly but worth it!
