I have had the nesco which was round and it was good but I just goe an excalibur and I love it. Drys so much faster with the fan in back and I can get more food on the trays. If you can get a used one I think that would be better. I dried apples and it took 5 hours. also dried peas and corn and am planning on drying carrots and potatoes next. Also a friend ddries watermelon and cantaloup , says it tastes like candy. Haven't tried that yet.
