Just got my XL about 10 days ago. Have used it 6 times and love it.
Right now it's just sitting on my pavers outside, but I started building a cedar cart yesterday. I reviewed the naked whiz plans as well as the large cart plans on the BGE site.

That's where I'm at after a few hours Saturday afternoon. Still need to finish the lower shelf, cut the hole for the egg, install the casters and slap on the poly. I also have a nice piece of granite to put on the table top for like a prep station type of thing. So far I haven't totally screwed it up and I'll be out of it with around $200 of materials. Pray for me.
I haven't purchased the place setter yet, but I have heard it's a must have. I got the electric starter, which rules. I got the rack thing for ribs or to flip and hold pork shoulders or whatever.
Anyone have any particular brand of tongs or grilling implements they like? I'm going to add a little grilling tool rack on the side of the cart and I have a lot of older stuff from my weber, but maybe there's something cool I don't even know about yet.
