Get an Excalibur. They often offer refurb ones with the same 10 yr 100% warranty for much cheaper on their website. Excals are the Lamborghini of the dehydrating world. I wouldn't trade mine for anything.

I've been referring to my Excalibur as "the Cadillac" of food dehydrators, but I like Lamborghini even better...
Phat-Take a look at the food-preserving@yahoogroups list. Ask their opinion of the Nesco. They may say it is worthwhile. I am not familiar with that one. I got a deal on an Excalibur on eBay long ago and love it.
Phat I have the Nesco Proffesional. I Bought it online did a search after reading reveiws. I went on Nextag and did best price search. With shipping it was cheaper than my local store. Later I ordered 2 additional trays and a couple more fruit leather trays. Do it they are great!
