Maytag Top Control Dishwasher 47dB with Stainless Tub - MDB7959SHZ $499.99
Just found and ordered this dishwasher through Costco (in Western Washington). This is easily $200-300 cheaper than other stores that have it on sale. This model has a stainless steel tub with large food disposal and runs at only 47 dB. Costco membership required. Bonus: Executive Members get a 2 year warranty on this. Similar model to other recent deals but likely more available. Also includes free delivery, installation (in some states) and haul away.
