Walmart offers the Presto Dehydro Digital Electric Food Dehydrator, model no. 06301, for $56.20 with free shipping. (Amazon has it for the same price.) That's the lowest total price we could find by $2, although most stires charge $65 or more. It includes six drying trays with expandability up to 12 trays, 90 to 165-degree Fahrenheit temperature range, and digital timer.
