A MUCH cheaper solution (and one I was forced into after an accidental batch of HOT Christmas cookies) is to simply buy your own set of dedicated cookie sheets. You might also try using foil. As far as the dehyrators go, I am sold on my Excalibur. It was a bit pricey ($200) but has thermostat, timer, huge amount of shelf space, and a heating element mounted vertically. I had a Ronco type but the juices all dripped down onto the heating element. Since there was no fan to circulate air either, they took forever to dry and needed the shelves rotated every few hours for even drying- ugh! Your oven is still your best and cheapest bet. Hope this helps! -Jim Campbell Mild to Wild Pepper & Herb Co In the midst of drawing up plans for a WALK-IN dehydrator. Tim Taylor would be proud! Home built & cheap too.
