I was looking for the same thing for my smokehouse. I went to appliance dealers who sell used parts; 2nd one gave me two brand new racks they'd ordered for replacements and the guy never picked up; he'd paid for them but never showed, and been kicking around for a couple years! Brand new and free! Also, dumps are good too, or find out from major appliance sellers (Conn's, Sears, etc.) what they do with the units they pick up when they deliver new.
