I did a thread on mine that I got from a yard sale. I saw it, wanted one for a while, it was there for the taking so I bought it, it's a Magic Chef so originally sold at places like WalMart. It hadn't been used, still in box, no instructions, but I got them via email later on. It doesn't rotate, it has 7 trays, I can fill it up with ease, and it's a sinch to use. My only complaint in that it takes quite a while, like two full days to dry thoroughly if you're drying things with much moisture like big seedless red grapes, but having said that, those dried grapes were the BEST!
I also did apples, bananas, pears, tomatoes, different grapes, and want to do celery, carrots, jerky, potatoes.
I'd buy it, don't think you can go wrong.
