Hi all, not a technical question but more of an opinion. I have an opportunity to purchase either a 60PS70 or a 60PZ750 both have very low hours. The PZ is a 3D TV that does not really interest me at all. I am more interested in picture quality and build quality. I have seen both and it appears to me the 60PS70 has the better picture but that could just be settings. Anyone knows the real "guts" of the TV's, there opinion would be much appreciated. Thx
