We just bought Nesco American Harvest FD-61WHC Snackmaster Express Food Dehydrator All-In-One Kit with Jerky Gun The Jerky gun realllly isn't neccessary.... but it's actually cheaper (more $ off) then the same machine without the gun (American Harvest FD-61).
I've made beef jerky, dried strawberries and zucchini chips since we got it.
The beef jerky (made from ground beef) was fab. Dried strawberries dry solid, but they are not crunchy. They are kinda like fruit jerky... gotta work at it (But so yummy). The zucc chips were nice but I used a little too much garlic and I sliced them too thin. Since veggies are starting to go out of season I'm about to dehydrate stew veggies for the winter (bell peppers, onions, tomatos, and I haven't decided what else yet).
I recommend getting a mandoline if you don't already have one. Makes prep work so much faster (and consistent which helps greatly with drying times... I remember cutting things with a knife when we had one with I was little and some things would over dry and some would underdry).
