JMS I've got a standard KJ and love it. There have been a few times that I wish I had a BigJoe (which is bigger than the XLBGE) but most of the time I've got more than enough room. If you got the adjustable rig from Tom at ceramic grill store you have more than enough room.
If you like the swing rack on the acorn you can order something simular from Franco at Ceramic grill works.
There is a KJ dealer near you. It's off exit 119 then north - a little hardware store with a good selection of accessories.
I don't mean to say BGE is not good in fact I think they're great. I understand they have improved their gaskets which was there biggest problem.
