I really want an Excalibur——my Nesco doesn’t get the slices really dry, unless I run the silly thing for 2 days. After 8 or 10 hours, the apple pieces are rubbery, and only last for a week or so before getting moldy.
A guy I know says he’ll build me a solar dehydrator...when he has time. Like, never.
We’ve found it to be a very good investment. We have the nine-tray model, bought about five years ago; they make bigger ones, but the one we have is excellent for our purposes.
