My girl has gotten used to me having the TV on when we go to sleep. I put it on sleep timer. I am actually doubting she will let anything bigger than a 46" into the bedroom coolface.Damn, that's big for a bedroom. I don't like watching tv when I go to sleep but my wife does and our 32" is so bright, I don't think I could handle anything bigger than that.
Use a wall mount.
many of them come with concrete anchors included.
Look for one on Amazon, probably about 200% cheaper than buying at a big box store.
I ended up picking up my un55d7000 for $1730 shipped. I just picked up the phone and haggled prices with several authorized dealers. Never pay the "online price", their is always room for negotiation. I ended up going with pauls tv. They had really good reviews and gave me the best price.
