I have a Nesco dehydrator (plastic, round, with plastic trays) it works great and cost 1/3 what they're charging for the Gear Guide one. Here's mine Amazon.com Nesco Dehydrator -- although I paid less than this for mine about 2 years ago. I only need to use as many trays as I want, and I can buy more trays separately if I want to dehydrate more food at one time.
I have seven trays for mine, and it's just about right to make 3 pounds of raw beef into 1 pound of beef jerky.
You make your choices, and you live with them. In the end, you are those choices.
