Yeah don't waste your money on that crap. You can get all of that information from public records. I once spent money on one of those services and they didn't give me anymore information than what I could have gotten for free. And to top it all off the info they gave me was out dated too.
www.verizon.com is a really good online phone book
www.anywho.com also is an online phone book, but an added bonus is that you can look people up and then you can get the addresses and phone numbers and names of everyone that lives on that street too.
Most states also have a website were you can look up criminal records by counties. I know Missouri has one, I'd assume that most other states have it too.
