I just sold my 65" DLP and was hoping for a good deal soon. I think I've decided on going 5" smaller and waiting for a good price on the Panasonic plasma. I can't stand clouding and flashlighting and crappy blacks and I've heard the Vizios have some banding which I think would drive me crazy. I would focus on it and it would be the only thing I would see. I'm going plasma. That's just me though.
I'm also looking forward to being able to lay in the floor in the living room and watch thanks to the good viewing angles of plasmas. With my DLP you couldn't do that, the picture was really dark if not right in front of it. Someone posted a picture of the 60" Vizio way off to the side and it still looked good though, so it may have good viewing angles too. Not as good as a plasma though I'm sure.
