I own two Nesco Garden Masters. I make Jerky all the time. The wife and kids love it. The deer burger jerky is what they prefer but we also get a quarter of a cow and have lots of hamburger to use up so I use that once the deer is gone. I also hunt for wild mushrooms and if I get a surplus of the right kind I dehydrate them. I have not tried too much of the other stuff, like fruit leather and dried veggies, but have always intended to because we hike a bit with the kids and always try to eat healthy on the trail and just in general. We don't want to teach the kids to eat donuts and chips everytime they are hungry. Our problem has just been time. The youngest is almost 3 yrs old and she demands constant surveillance because she can reach the door knobs and loves to be outside.
The Nesco Gardenmaster is around $80.00 and you can get extra trays if you like. The only reason I have two instead of extra trays is that it was on my Amazon list and both my wife and mother purchased it. I like having both though. One comes with 4 trays and will make two pounds of burger into jerky without extra trays. Sometimes I make 4 lbs and use them both. If you add trays I imagine it slows down the drying time.
I keep mine in the original boxes on a shelf in the basement.
