Now Then - The TV Dilemma Part 2: 1080p or 720p?

Thanks to all those who helped with finding me a TV that fits my criteria. But now I’m REALLY debating whether to get a 1080p or 720p.

I am not picky about this kind of tech, and ANYTHING would be an upgrade from what I have now (old ass CRT)..... but I will be getting a PS3 soon (should that be the only determinant that makes me get a 1080?).

Other than that, I don’t really know whether I should spend extra money and ‘settle’ for a low-end brand just to get a 1080p OR go ahead and save the money and get a decent 720p. Need your thoughts, insight and good reason to go one way or the other.
