Best Black Friday 46-50" LED 1080p TV to get?

I am on the market for a new television that is around 46-50" range, namely just want it to be LED and well 1080p. I don't care if it's a smart TV, as that'll drive the price up, plus it'll be connected to an xbmc htpc so that's covered as well.

The last TV I bought was 5 years ago, a Samsung 32" LCD 1080p TV that still works but had to part ways with it back in April as I was worried it wasn't going to make yet another move so I'm not very knowledgeable in what's out there now, especially with the sales on TVs this weekend..
Thanks for any advice or links you may have to provide towards specific items on sale.
