While we wish we could get the full-size 800 with Crystal Dry, it would take too much space in our small kitchen. This 300 series has been a great alternative. It hold enough dishes we only need to run it every other day, so we are saving money on water and pods. The Auto mode works great at getting dishes clean (much better than hand washing) and it has been so quiet (as long as things don't touch and clank together) that we run it at night.
On thing to be aware is this is also ADA compliant, so we used 2x4s and plywood under it to bring it up 3 inches to regular countertop height to reduce bending over so far when loading and unloading.
