I have a Mitsubishi 55819 55" HDTV I have had for about a year. I love the set, and regularly calibrate brightness, contrast, color, sharpness, and convergence with the THX Optimizer. I think its time to go into the big-leagues, though. I am interested in finding out who I might contact about ISF calibration in the Northern Virginia area. I primarly watch DVDs, about 95% of the time, the other 5% being Xbox or Playstation 2 gaming. I don't watch any other sources, no HDTV for me yet. Anyone have any suggestions? How about an estimated cost? Thanks!
