Yak, I do not have anything very nice, and I do NOT want to take this off topic, since that is the point of the title, but my buddy has a Lynx set up like the Snoqual referenced which is very nice, but my tiny exposure to high end grills makes me remember the infra-red rotisserie on Phil's grill.
That is one sweet add on.
Good luck with your search
