I'm interested in getting a new plasma TV for my basement. With the media center I have, the largest plasma I can fit is a 59" Samsung. I'm currently debating between the D6500 and D7000, but I haven't been able to go anywhere to see these two sets compared side by side. I compared the D7000 to D8000 side by side, and couldn't tell a difference in picture quality, and the web browser isn't important to me. My basement has one window on an adjacent wall about 16' away. How much of a difference in picture quality is there between D6500 and D7000? Is it worth the extra money to get the D7000?
