We recently upgraded to the Bosch 800 series and couldn't be happier. It's super quiet and does a fantastic job of getting our dishes clean. It saves on clean-up time (and water) because we don't have to rinse the dishes before we load the dishwashwer like we had to with our old one. Love the third shelf, too, for those extra odd-shaped items and knives.  Our dishes look and feel as new as the day we got them!
