David, the CR ratings you looked at last year(the most recent dishwasher tests)probably included this discussion . The Kenmore Elite was top-rated, but the model more in line with the budget you mention is the Bosch Ascenta model which was also very quiet. The models which don't have a grinder(which makes, not surprisingly, a loud grinding noise)to make the filter "self-cleaning", are the quiet ones.

Enjoy the music, not the equipment.
