Im planning to buy the good4u 6 tray dehydrator and it comes with 2 non stick sheets and 2 mesh. Should i look at ordering more when i purchase this. I am new to dehydrating so it will take me some time to learn it. The non stick trays are reusable correct? So if i wanted to fill up all 6 trays at a time then i would need 6 sheets? I plan to start with dehydrating fruit and i also have alissa's latest book and alot of the recipes require a dehydrator. I also own a vitamix 5200 and manual juicer. Does $150 sound like a good price for a 6 tray black with 2 non stick sheets and 2 mesh and free shipping.
