I'm seeing the 70 inch 732 in a couple of places in NJ for $2299, and the 70 inch 6400 at Costco for 2499. I'd prefer to get at Costco so I can relatively easily get it home, and return if necc with issues. Plus an extra year warrant is nice. But I'm happy to save $200 and maybe pick up an extended warranty perhaps for 100. And I like the idea of getting some of the extra features the 732 has, like that magic yellow pixel George Takii talked about. But I've pretty much convinced myself that the benefits of the 732 aren't really that great to justify any price increase over the 632, and figure the 6400 is similar.
Thoughts? 732 vs 6400 in a 70 inch? I guess that the price is comparable enough that I should get the better tv? But which is better?
