Installer just left from installing my 811. I have to say, the 811 outshines the 6000! I have read and heard horror stories about this unit, but so far, it is outstanding. As far as the dark picture everyone is talking about, I am not seeing any dark picture whatsoever. It seems the HD channels are more vibrant and full of color. Maybe a turn around for the 811 eh? Defiently impressed so far!
