with fan - another important feature - and it's great.

I have a DAK turbo dehydrator that I bought from Sharper Image years ago. I don't think they even make it anymore.

Lot's of good models out there driven by more and more people getting into dehydrating for a variety of reasons.

Whatever model you get, make sure it has a FAN.
Older models basically just had a heating element and to get the most efficiency out of them, you needed to flip thicker items ( jerky etc) which is a real pain.
The fan feature eliminates that as long as you don't crowd the trays.

  I also bought extra trays and when doing jerky of any kind, I put an empty tray between loaded trays. It seems to speed the dehydration process.

Biggest problem making homemade jerky is the smell as it's drying. Hard not to over sample. ;) ;D
