Here's the set I'm looking at. Circuit City has it on sale for about $550. Will I need a receiver to watch cable TV on this, and/or play X360 in HD? Can anyone recommend for or against this? I've heard the screen is produced by a different company than the 27" version and is of higher quality. I'd be picking it up locally, but I hate dealing with Circuit City when I have problems (which, with them, is often). I'm also concerned about dead pixels. When I spend money I like the stuff I buy to be flawless, particularly when it comes to things like dead pixels.
