I used to have one, but unless you're really serious about using it I wouldn't bother - it takes forever to dry things out!
I tried making a few things in mine - most notably banana chips and beef jerky. The banana chips took 55 hours! I have a dehydrator cookbook somewhere if you'd like it, I forgot my dehydrator when I moved :-( so not in need of it any more.
Meaty things absolutely stink the house out too.
