I just purchased the Quiet Partner III.  I wished I had not.  It is quiet for a reason and the reason is not because of superior sound dampening.  The reason it is so quiet is because the pump is next door to worthless.  It is a poor pump that barely squirts water.  To get around this, they run the cycle longer... much longer.  The idea is, that given enough time, the moisture on the dishes will soften any food and clean them.  If you have any stubborn food, it will be there after the cycle ends... (usually 2-3 hours later... NO exaggeration!)

The insulation package was very poor; it didn't...
