I have bought a couple different ones. Usually the home style ones are a bit flimsy and the ones I had bought the motor would bog down a bit. Even these ones can be a pain to clean. One of the ones I had was the Rival one listed above.
So far my thoughts on this 615 model is that it is awesome!! Did some roast beef. Turkey. And sliced some round for jerky. Worked flawlessly and ezpeezee to clean!! So far i say this model is a winner!!
