The American Harvest/Nesco Gardenmaster Dehydrator
I found this here. Don’t remember who posted it.

I have a NESCO with six trays, and it works just fine. I think if I had a garden that produces a LOT of produce, I might invest in something bigger, but this one is fine. Since dehydrated foods shrinks up to itsy bitsy pieces, make sure you have screens that will keep the food from falling through. I know with NESCO you can buy mesh screens to fit on the trays.
