Bosch is nice, quiet, and most importantly been junk lately.
Our Bosch was the most troublesome dishwasher we ever owned. It broke down several times (all electronics) and the last time it finally crapped out, the Sears warranty kicked in and gave us a 500 dollar credit to a new one. Got a kitchenaid, and no problems for a year...
AVOID MAYTAG LIKE THE PLAGUE! They have bad electronics that like to randomly crap out.
