I am on several HDTV forums, I suggest the following for possible technical information, (you may have to navigate to different areas of these forums), I prefer satelliteguys.us for most information, but they all are good.

BTW: I bought a Sony 34" XBR (CRT) TV in April (paid $2k then, now they are a few hundred $$ cheaper), great picture and the picture tube is "super fine pitch"!!
If you have any questions, please freepmail me.
And thank you very much!
