Samsung LN52B750, I just received my LN52B750 this week and have to say it is simply an amazing display of the high definition experience. For the price, this LCD is a great value IMO - and not just because I purchased it, I shopped around for about 1.5 months and could not find a better LCD with the features this set offers.
A friend has last years LN52A750 and I can honestly tell the differences and upgrades to the 'B' model - such as the increased contrasts ratio, 240Hz refresh rate and the improved Media 2.0 USB functionality.
If you are looking for a decently priced LCD (with higher end features), this is the TV for you!

Pros:
-Picture quality is stunning- need to see it in person to appreciate it.
-Functionality of Media 2.0 (USB) port is improved and very useful for looking at picture/movie files and music.
-Swivel stand is convenient.
-Charcoal TOC is far more subtle than the red on other models.
-Shipping and delivery was spot on through Amazon.

Cons:
-Sound quality (honestly isn't THAT bad; get a nice surround sound or sound bar and the issue will be moot).
