I started out asking about LCDs in another thread, but thought I'd start a new one for plasmas. I know I want 1080p, but don't know how to figure out which models have the best picture quality or usable features. Are the newer models really worth the extra money? Unless there is some kind of much have feature coming out in the next month or so I'd like to get the tv soon. It would be great if I could have it setup in time to watch the US Open in high definition.
