Use the Amazon Warehouse for better pricing on used models. Have the same warranty and most are new or in like new shape for a lot cheaper just missing the manul or original packaging.

If that is too expensive for you I highly recommend this one as a starter. It will do about 3 lbs of jerky at a time and the trays are dishwasher safe. Digital temp to 160 and 24 hour timer.
