Hello, all. I bought this TV recently when it was on sale for $398 at Circuit City--a real bargain, I think. I've been really happy with the set--no ghosting or geometry issues, as some have mentioned. I'm using it for XBOX and Gamecube right now, and the games look great, especially those that support 16:9 like Burnout 3, Chronicles of Riddick, and Eternal Darkness.
Some have requested picture settings after calibration with AVIA. I did my calibration tonight, and here are my numbers. Remember, lighting conditions can change these numbers, so they may not work for you. For me, calibration resulted in a picture that is less vivid/saturated than the default settings, but which displays FAR more detail and subtlety. I can see every little detail on the costumes in Lord of the Rings.
(The color mode is set to "normal" rather than"cool" or "warm"; natural color is "off")
Hope that helps. In sum, I highly recommend this set. I can't wait to get a PS3 next year to try out the HDMI input!!
