Assuming it is a Touch 'n Go performer (thus designed to have a tank), the lack of that tank kinda sucks, but is a very strong bargaining chip. Without the propane light option, it is basically a simple black kettle with a table (albeit a very nice table). If the kettle, ash cleaning system and cart are all in great shape, I'd offer $50 and might go as high as $75. If not, I'd obviously aim lower. Of course, value is truly subjective, so much depends on how much you want the grill. The number of folks willing to buy a used grill in December might also work in your favor, as there may be a very limited market for the seller. Good luck!
