Thanks for the input Richard in SF and millerwill, I was leaning toward the 56" if it had a sharper image because I thought that once I got it home, and it wasn't next to a larger television, I would never know the difference. Do you know if the difference between the two would be very great? If the difference between the two is negligible, then I would prefer the larger set. The larger would be very nice for playing multiplayer GRAW, and for watching the playoffs, NFL, March Madness, etc.
One follow up question: (this is random) is there anyone that has this TV that watches Law and Order on TNTHD? If so, how does it perform when displaying the dark scenes? On my current Toshiba you can hardly see what's going on, I have messed with the calibration and no matter what I do the picture is either too bright during the day scenes, or too dark during night/indoor scenes.
