Not knowing what states or years you are looking for, it's hard to say what exactly is offered by the site you mentioned. The site itself states:
• Possible Marriage Records
• Possible Death Records
• Possible Obituary & Cemetery
• Possible Criminal Records
• Possible Court Records
• Possible Bankruptcy Records
Some states make their records available for free; some charge; others have date restrictions, etc. I subscribe to Ancestry.com but again, if the state laws restrict the vitals, Ancestry won't have them either.
When I want to see if vitals for a particular state are online, I usually visit the following two sites. These are free sites, on which are posted links to other sites. The compiler usually states if the other sites charge, or are free. Don't let the "germanroots" in the website name mislead you; it covers all people.

http://www.germanroots.com/deathrecords.htmlFor recent stuff like people's addresses, I usually use
www.pipl.com. This site links to other databases, some of which you must pay for, and others that are free. Pipl.com connects to databases that can provide addresses, phone numbers, email addresses and more. You do have to determine which of the "hits" may be yours, and which are not. Pipl will gather everyone with that name; it can't tell you if that's the person you want.
As I said, some states are better than others. For instance Florida has myfloridacounty.com on which you can find marriage and divorce info, court records, etc. Sometimes a county clerk's website offers more information than a state does.
