I'm looking for a 50" plasma soon. I know that Panasonic came out with a new one, LG, and I think HP a couple months back. Does anyone know which has the best picture? The worst thing about plasma that I've noticed is the shading problems with some blacks. It doesn't make the picture look natural. It's graduated I think is the term? Please help. I'm looking for something that recently came out or will soon...cause I might as well. and 10,000 to 1 contrast ratio sounds nice. Thanks.
