If you have an extra 30 bucks, an even better option would be to get the newer Panasonic 42" S2 which can be had for $532 from 6Ave.com with coupon code AFL3. While slightly over the $500 mark since there is no tax or shipping cost I assume it would be cheaper than walking into a retail store and buying a $500 set+tax
