I work on the principle that if I want a bit of kit - might as well get the best I can afford. The excaliburs are real nice dehydrators.
Beauty of it is I can go down to 35c for making proper biltong (which breaks all the rules of american jerky) or up to 68 for making snackstix.
Plus when i got the dehydrator you couldn't buy the cheapo flying saucer types in the uk.

Which reminds me - not tried alexa with nylon yet.
