I think the 55" version of that was sold during Black Friday for $500.
The lower end model is stripped of the 120hz motion options I think. Other than that they are the same exact panel.
Picture quality is pretty mediocre.
I would go in store to see them in person before buying online, you might regret it after seeing how it looks.
You were right the picture quality of that TV was abyssmal. Then I saw plasma and fell in love. Unfortunately Panasonic is completely unavailable, so can anyone recommend me a plasma 1080p in the 42''-50'' range?
