Thanks - this is just the info I needed. I first started thinking about dehydrators after reading posts from both Georganne (LilaLoa) and Jaci (Ali's Sweet Tooth). I had heard about the "dip" towards the center from others as well. I may not decorate as much, since I don't sell...but if Texas's governor signs the new home baker bill sitting on his desk, I'm thinking about holiday sales at our South Padre Island Farmers Market. That will make me rethink having to set up 3 or 4 fans around the house... a dehydrator will be greatly appreciated. I even got a heat gun for Christmas from my son... that was a flop for me, very bulky and unwieldy...HEAVY. I gave up after two decorating sessions. Thanks again for your great answers!
