So the main differences between the CB and the Weber are that the CB has a SS ring, a battery powered motor, and the ability to use on both a kettle and a 22.5 WSM.
The Weber has a black ring and comes with an AC motor.
Accesories like the Rib o Lator will work with both units.
Does this pretty much sum it up for the most part?
I only have a 18 WSM, so the versatility of the CB doesnt really apply to me. Also, I can get the Weber locally and not pay any shipping charges. Unless I missed something major here, I'm leaning towards the Weber unit.
