I don't play any video games either..... I was just making a rash generalization loosely veiled in a Stereotypical falsehood based on your age.....
Either way.... sorry about that.
Either way.... For a bedroom, a 40" T.V. would be pretty big (Heck, other than the projector, I only have a 37 and 32" because we don't want anything "Too Big" )
Either way, I know it's personal preference at this point, but perhaps look around the Plasma, and LCD section here, and find what else is out there for $600 or so....
I really just don't care for RCA
