I do have the six-drawer Excalibur, and really like it.
Things I've made and liked: zucchini chips, sweet potato chips, dried grape tomatoes (slice in half), dried strawberries (slice to 1/8th inch or thereabouts), lamb jerky. Asparagus (I dried it, ground it, and turned most of that into soup).
Things I've made and need work: kale chips - not quite ready for prime time! White potato chips - unfortunately I'm so ingrained on the bad-for-you potato chips that these healthier things leave me cold and disinterested.
I want to dehydrate onions, along with the above successes, again this year. And try kale again.
A lot of dried fruit I dislike to begin with (texture and concentrated sweetness), and I have no desire to chew through overly-sweet fruit leathers.
