Oh, and for what it's worth..... this is the TV I own:
Dell 37" LCD
I did win it; so the price was right. It often goes on sale for $1799. The only time I have ever noticed an issue that looked like a response time problem was watching a CBC CFL game. Watching football on TSN, NBC or CBS so far this year has been perfect.
My only complain is the size. 37" gives me a 31" 4X3 picture, and my old SDTV was a 41".
