Either go with the 46" Samsung or this 47" LG:

Spend some time with the remotes of both units to ensure that you feel good about the ergonomics of the unit you choose - people forget about this aspect of the TV and yet once you purchase the set, all your activity will be through the remote!

LED sets are cool and energy-efficient; most plasmas still generate enough heat to raise the temp of the room a couple of degrees when on.

I agree with others: We tend to size a bit small in our minds. Go one size larger than you think is right and you will be patting yourself on the back for years.
