What is the best size & brand of flat screen TV to mount over a fireplace? - flat wonderful peach

I have a family room with a beautiful fireplace that stretches cieling floor. I intend to mount a flat screen TV on the TV screen. The sofa is about 10 + feet of the chimney. The room is on the darker side, because they do not receive the sunlight. What type (LCD, plasma, etc.), the size and brand is best for my needs.
