You see these pop up from time to time. I'd say this is worth the $500 asking price...it's a clean machine, and in my fav color yellow. Are those 2 or 3 rotisseries in there?
It could either do a rotisserie item like a roast in the central position or shish kebabs on multiple skewers. I just hope that enclosure had a very powerful ventilation system to cope with all of the heat when that was in use.
