We have the L'Equip 528, and I love it! We didn't pick it special, it was just one my bus. partner had and had forgotten about. I love the rectangular trays because they fit perfectly into our baker's rack, and the temp options are great(even though we only use it on the lowest setting). It's made a huge difference in decorating for us-I can flood a cookie, throw it in the dehydrator for 5-10 minutes, do top level detailing, put it back in for a few more minutes, and there's absolutely no bleeding. It really helps with the drying process as we're in a humidity nightmare location too. Definitely one of the best tools we have!
