I've been also looking to buy a new tv for the basement.

Everything I see keeps pointing me back to a Panasonic Plasma.

The 46" that you mentioned is $1118 with free shipping on Amazon.

I have been thinking about getting last years model and going with the tcp58s1 which is about $1400 or I can get the tcp54g10 for $1400. Still deciding if the G10 and thx is more important to me or a larger screen.
