OP - Why are you buying at Walmart ?
The best deal in terms of value for your dollar is Toshiba (who invented DVD and HD-DVD), and Walmart does not carry them.
The best and simplest way to figure out which TV to get is to spend some time reading the customer reviews on Amazon.com
As a general rule, Samsung, Toshiba, Sony, Panasonic and Pioneer all make good sets (although IIRC Pioneer is beyond the budget of most of us here).
Lastly, remember that a Plasma usually uses more electricity than an LCD, so it will cost you more in the long run.
