Hi everyone, I am in the process of selecting a 50" rear projection TV, either DLP or LCD. If I go with LCD I have it locked down with Sony. I am leaning toward DLP and I really like the look of the Toshiba set. I am also considering Samsung and Mitsubishi. How do these sets compare? Does DLP still have quality control issues? How bad is the high pitch noise from the color wheel that I keep hearing about?
