Got mine from Newegg. Saved me over $500, didn't have to pay taxes and their price was cheaper than Bestbuy etc. Plus it was free AIT front door delivery, which took 2 days.
Seconded. Go to Best Buy, stare at the wall, find one you like, then buy it from Amazon. Not only will it be significantly cheaper, but it's tax-free. You might have to wait a week or two, but delivery is free, and it's white glove service, door-to-door. Great deal, usually.
