I have an Excalibur. I have the economy one with 5 trays and I wish I would have got the one with more trays. If you get the one with more trays and you have taller stuff to dehydrate you can leave out every other shelf. I also bought the silicon pads that fit exactly on the trays, it makes cleaning a breeze.

One of my favorite cooks recommended the Excalibur, she also has the optional glass front door.
Two Onion-Flax Cracker Recipes from the Dehydrator - YouTube
One of the foods that really works good in the dehydrator is Kale Chips. I buy 2 bunches of kale tear the leaves into about 2" pieces and it fills up 5 trays. I double the recipe below.
Recipe:
1 Bunch of Kale
1 c cashews (soaked for an hour)
1 medium red pepper
Juice of half a lemon (2tbs)
1/3c nutritional yeast
1 Tsp salt
1 Tsp apple cider vinegar
(Optional taco/chilli seasoning - for nacho flavored)
Directions:
Wash kale, remove stalks, tear into even sized pieces (approx 2 inches) place in large bowl.
De-seed the red pepper and drain off your soaked cashews.
Put all ingredients (except kale) in to a blender and blend everything together.
Pour mixture over kale and use your hands to toss it all together.
Set dehydrator at 125˚ for 3-5 hours flipping once after a few hours.
(These chips can also be bought at Whole Foods store at $59.00 a pound.)
