I am also tempted by the significant price drops on the 62U since they are now considered clearance. Anyone see anything fundamentally wrong with the 62U vs the 64U?
Just that the contrast ratio is pretty weak. And there's always the banding, but of course there's no guarantee that the 64Us won't have that too.
And I've heard some scattered reports of problems with audio passthrough on the 42D62U, but I don't know the exact nature of that issue. It sounded pretty annoying, in any case.
There probably isn't much potentially unsatisfactory about the 62U that you wouldn't be able to decide for yourself by seeing it in person.
