There is a guy with a stove shop that used to advertise Kamado Joe on CL, he's also a Primo dealer and owns a L-BGE, I talked to him at length about them and he just wanted to have something more to offer customers. He said it was one of the first grills customers gravitated to because of the color. When asked about cooking differences between the other ceramics, he uses a Guru and noticed none. He had concerns about welds on the steel parts of the KJ and lack of dealer support from the manufacturer/distributor. He no longer advertises the KJ and its been a long time since I've seen any Kamado Joe offered on CL along the I-5 corridor.
At Whistler, BC there were a few of them being used by teams and a dealer and I know a couple cooks that won them at contests in Canada and they like them (wouldn't you?).
I sent a couple requests for info through their website when they first hit the scene here in the Northwest and never got any responses.
That's my review, I also touched one.
