I have a 4 tray dehydrator that I got at Cabelas about 5-6 years ago. It's still going strong. I think I paid about $100 for it. I just looked at their website and it was on sale for $16, yes, that number is right. Sold out which is no surprise. However, here's a newer one which is better and still cheaper than I paid years ago:http://www.cabelas.com/cabelas/en/te...=cat570005&rid
I use mine mainly for drying peppers. The thinner the wall, the faster they go. However, I dry anything from Thai Dragons (thin wall) to Jalapenos. I also started doing Jerky this year and can't believe I waited so long. For Jerky, I set it about 130-135 degrees and it takes 6-8 hours depending on outdoor temps. I keep it in the garage. It does a great job.
I flip the jerky every two hours and rotate the trays every two hours. It's not a problem for me to keep track of. I do whole meat so if you're doing stuff out of a gun, then you should get some screens.
A dehydrator is one of the best pieces of gear I have.
