2 months ago I a bought a 46" Samsung from Amazon. First big screen and I love it.
Free white glove delivery, and the price was $275 dollars cheaper than Best Buy. Your mileage may vary but I ordered the tv on Saturday, and received it on Wednesday. Delivery guys will even take the box with them if you'd like. Great experience overall.
Here's the TV
