Bought one last week together with a friend, and both PW's are perfect (205 series).
No colour blotches, no light leaking, a beautiful even screen. Very faint gray shadows just above the leds, but that is hardly noticable and completely normal I think.
I was prepared to accept a screen with some issues, because I love the lighting so much. The one I got exceeded all my expectations and I'm hysterically happy with it.
As long as you can send back a PW that isn't up to par, I'd say try it. If you have a good one (or if you can live with some imperfections) it's a huge improvement over the K3.
