Question about HDTV (link inside) lag with fighting game

I am looking to buy this SONY Bravia HDTV, and I wanted to find out if any people who post on these forums have experience playing games on this model. I mainly play MvC2, and I am looking to upgrade my TV, but am concerned that there may be some input lag (due to the refresh rate of some HDTVs).

In the past I have played on other types of HDTVs, and there has been a slight amount of lag, that makes a world of difference (in a bad way) in MvC2.

There is a thread for this topic. You might also want to check out the Input Lag Wars thread at avsforum.
