I just bought the Vizio 70" at Costco, for $1,665 with tax
But they also have a Samsung 64" (Plasma) for ~$500 less
It's a big difference for 6".
Of course, the bigger screen the better.....but $500 difference is huge
Not sure about the ref for the Samsung....I think it is PN64E533 D2
Vizio is E701i-A3
The Visio reviews are pretty good as long as it's in movie mode. Black levels aren't the greatest but it's an LCD. Couldn't find anything inthe Samsung. Being a plasma I'd ASSUME it has better blacks but can't be certain. I bought a C550 a few yrs ago and returned it because I wanted better blacks and picture adjustments. It also had a weird thing where it'd change the zoom depending on what I was watching and would have to reset it. Traded it in for a c7000 and it has a much better picture (minus the pink banding that I'm now seeing and will be getting the panel replaced.) if you like the picture on the Visio I wouldn't hesitate to keep it, especially since its so much bigger. If not, go plasma. I definitely believe that the higher end sets do give a better picture but you just have to decide if its worth it to you. I also spent an extra $500 to upgrade so...
