Displays and Projectors : Looking for 40 in. LCD Recommendations

Looking for 40 in. LCD Recommendations

I want a 37-40" LCD at 1080p what would you suggest? I would like to stay in the $1200 to $1500 range. I am worried about blurring durring high speed action sequences (fights in the Bourne Identity for example).

I think I want to go with Samsung or Toshiba but i'm not 100% sure. Any suggestions would be most appreciated.

PS do upscaling DVD players really make a big difference when viewing standard DVDs on a high resolution screen? I have hundreds of DVDs and would hate to have to replace all of them on Blu-Ray discs.

Thank you for your time.
