Reverse Phone Lookup

LOL, it isn't a big deal at all. I just couldn't think of his name and then I rememered using reverse lookup sites in the past to lookup missed calls I reveiced after losing all my cellphone numbers. Back then I remember the sites working for the vast majority of the numbers without charge, but now things seem to have changed.

Which reminds me of something else that is related to this thread...anyone do online background checks? I have run a couple of them in the past whenever new close contacts strike me as shady. But is any one service better than another?
