I brought my dishes into many stores to find a DW that fits tall things on the bottom rack, and this one seemed to have the most clearance, as well as a 3rd rack that doesn't fit much but silverware.  I've only run it twice, but things seemed to come out very clean---even pans with some baked on grease.  Only downside is that the bottom rack doesn't have enough tines to hold small casseroles that can tip over.
