I know the Grobo has a drying time built into its system, but I also have 2 HerbsNow for sale.
1 has never made it out of the box and 1 was used twice, but I still have the original box. Super easy and 100% reliable dehydrator.
They list for $150 and are backordered on most websites. I would sell both for $100 with buyer paying shipping costs. Or 1 for $75 with buyer paying shipping.
