I'm also a big fan of the Big Green Egg, The ceramic provides the insulation that the Weber is missing. Also thank you for being so articulate and not responding the way the majority of the users on here do it, was quite refreshing having getting a well though out and mature response for a change.

Price is part of it. the other part is a tried and trusted design. There's a reason that 2 of the others on that list use a similar design just adding ceramic to the mix.
