Just to add, I went through this whole debate between the 46" Sony, the Samsung UE46B8000 and a KRP-500A. Price, size, partner approval all came into it. In the end just couldn't help but realise that the picture on the Kuro was second to none. No matter which other TV I looked at in the shops, if there was a Kuro in the room, all I could think was "Is the picture as good as on the Pioneer", regardless of source SD / HD, etc.
And my partner agreed...
My KRP-500A was bolted to the wall on Tuesday and the cost was about the same as sgrant01 has been quoted and I can say it was worth every penny... All I can think about at work is what I can watch on TV tonight, even with the screen with lousy contrast for 200h run in. I feel like a child in a toy store.
