Everyone I have talked to LOVES their 4311CI for sure. It weighs in at 38.2 Pounds, does that say something vs. 26 Pounds for the 3312? To me it does...but will cost you 1/2 again as much.
With the new In-Command Series they are after the Streaming and Enhanced Net features (DLNA, AirPlay, RadioDenon, etc.), and the front end GUI Wizard looks great also.
What do you think of OPEN BOX Buys? You've had experience with those, since you have made a few right -- great idea?
