I've just started preserving (only water bathing at the moment), but I'd like to get into dehydrating, things like onion, garlic, herbs, fruits.

What is the best dehydrator to start with?
I know I don't want a round one (from what I've researched, you need to swap the trays around throughout the process), and I want stainless steel racks as I'm trying to refrain from plastic as much as possible.
