I've been using a Weston Vegi-Kiln Food Dehydrator for about nine years now and it has been great.The heat is adjustable 95-155 degrees and the fan and heating element is in the back of the unit.This design is way better than the stack models.I have dried hundreds of pounds of meat on it over the years and still works as good today as it did when I first got it.

As Bob Hagel would say"You should not use a rifle that will kill an animal when everything goes right; you should use one that will do the job when everything goes wrong."Good words of wisdom...............
