Lots of choices. My 65" RP Hitachi I bought to watch the Masters the first year they broadcast in HD is still going strong. Here's one that is about the same price as the 52" Sammy I bought about 4 years ago:

Amazon.com: Samsung UN65EH6000 65-Inch 1080p 120Hz LED HDTV (Black): Electronics

If you buy it online, I can recommend Amazon, where I bought mine. They have great customer service. Make sure to buy it directly from them and not a 3rd party on their site.

Only has 2 HDMI inputs so if your receiver isn't doing your HDMI switching and you need more than 2, you probably want to look elsewhere. Also, you will probably want a universal remote. I'm not a big fan of their remotes and this one gets bad reviews.
