Pulled the trigger on a Cabela's unit that is large enough to meet our requirements. Ernie's success with dehydrating influenced us in our decision to seek an additional way of preserving our produce. We will finally be able to save all our potatoes & onions. Also want to try some tomatoes!!! The 160-liter model has 24 (21-1⁄2" x 16") racks for a total of 56 sq. ft. of drying space & produces 1,600 watts.
