We have been pleased with our Bosch 500 Series dishwasher. It cleans very well (we are still getting used to not hand washing everything before putting it in). As an experiment, we have put casserole dishes in with minimal rinsing, and they come out totally clean.  We love the 3rd (top) rack and the Auto-Air feature which pops the machine open at the end of the cycle.  It leaves plastic stuff is a bit damp, but we decided we can live with that given the other excellent features.  I looked at the higher end models with the CrystalDry technology, but that didn't seem worth the extra cost and several reviewers said it is expensive to service if there are any troubles.  I installed this machine myself, was not too hard to do.  As advertised, it is very quiet.  We used to have to set our old dishwasher to run at night when we were asleep, but now we can run a load of dishes while we have guests in our adjacent open living room.
