This is the one I have. It's last years model, which I see has gone down in price quite a bit :fuuuu: When I bought mine it came with the bluray player/glasses/movie promo too which was a nice thing to get. I don't think I've ever seen a TV with a nicer picture.

It has apps, and it has a higher refresh rate than the samsung you have listed. The one you linked says it has skype, but I'm unsure if it has Samsung apps, which is nice to be able to have Facebook/Google Maps/Youtube/Netflix etc built into the TV. A nice little bonus is that you can install the samsung remote app on your android/iphone and use it as a remote through wifi.
