I'll second the Walmart dehydrater. I made my whole deer into jerky.

Lately, I've done a 2 stage jerky drying,... I put it in the oven for a couple hours at 200 degrees, until it is dried enough that the jerky will stay together when I pick it up. Then I put it in the dehydrater trayssetting the jerky strips on it's side.

Doing it this was, I can put 5 pounds of jerky on 2 trays in the dehydrater, which will help speed the process.... since using alot of dehyrator trays slows it down.
