Product review (4 stars): Good DW, quiet, runs great.
We replaced our 10 year old DD-603 with the newer model.  We really like the 2 drawer concept when we were but 2 people.  It would take us a week to fill an entire dish washer!  Now that we are a family of 4, the concept still works well for us, living out of one drawer while filling the other ;).  Seriously though, its much quieter than out original and works very well.  The newer display takes a little getting used too.
