I recently purchased the Kitchen Living Food Dehydrator for $19.99 at ALDI. There are a few left in stores, so worth snagging if this is your thing. I have never dehydrated foods before, so I am by no means an expert on what makes a good food dehydrator. I have had quite a few zucchini, summer squash, and kale from my garden this year and last and I was looking for something to do with them other than freeze. I have done a few batches so far of zucchini chips (Yum!), summer squash chips, and kale chips (I am not a fan. I really don't get what all the fuss is about?) I also just did a quick batch of drying italian parsley, basil, oregano, lemon thyme, and greek oregano. It's a fun new kitchen gadget to have and I am happy with my purchase.
Price: Similar 5-tray, single setting, food dehydrators are priced $30.99 at Target and $40.99 at Walmart. Steal at ALDI for $19.99.
Drawbacks: Other dehydrators have temperature settings, so you can adjust the drying process. For my purposes of trying out food dehydrating, this was not an issue for me.
