Sagem 45" TV Versus the rest
 

I am about to finally get a big flatish panel TV. Only want to go to about 40" max but this Sagem thing seems to have a great picture running HDTV. Is the picture going to downgrade loads on cable and DVD. Also anyone got any views on what is better, this new Light Projection or plain old Plasmas. I want to get a TV that isnt going to be out of date in a years time so any advice on what spec to look for would be appreciated.

Cheers all
