fyi: if you're looking for the big 6 rack rib-rack (non-stick), I just saw some at Home Depot for around $9. Not sure how many HD's have them nation-wide...
I got one of those a couple years ago. It works ok,but I haven't used it in the couple of years since I got my WSM. The last time I used,however, the non stick wasn't doing so well. I guess you get what you pay for>
