CIS Worldwide appeared to be very professional and well established public records database site. I accessed the site claims to public records for a one time fee usually $39.95. However this is misleading, what you are paying for is "credits" to do different searches for public records in their database. So in terms of "unlimited" that only applies until your money runs out at which time you must purchase more "credits". All of this information is laid out in their terms and conditions, but could be made much clearer up front.

With that being said, when you access their website each search is labeled with the amount it cost to perform, and if no results are returned then you are not charged. But it will give you results of people with the same name of the person your looking for but not the correct person. I received no information on the person I was looking for and no way to contact company for help or refund.
