Chris in LA is right on. Stubbs original sauce is on the tart vinegar side and a delicious alternative to the sweet red sticky stuff like SBR and most others.
I use my Baby Q much more than my other grills. I mostly just cook for the two of us and my Q100 is usually large enough and quite capable for most of my outdoor cooking. It's been my main Que for over 6 years now. Tonite I babycued a deep dish pizza in a 10" cast iron skillet.
I have looked at the Chargriller kamado closely at Lowes. The removeable ash pan clamps on snugly (doesn't slide) and appears to seal very well. It has a good quality cast iron grate with a removeable center.
