RCA DRD420RE DIRECTV PLUS Second-Room Receiver
No problems
I've had two of these RCA 420RE's for about 18 months now and have only found one problem with them.  The thing I found was that the remote works best with fresh batteries.  When the batteries start going down some buttons may not work.  I find the menus easy to use.  I have friends and family with other receivers and I think the 420's menus are as good if not better.  After reading the other reviews I will be knocking on some wood though.
