I was contemplating a signup to the following for marketing purposes, not especially for bkgnd checks. It's fully guaranteed, staisfaction-wise. Beyond that, I have no personal experience with it. I never put much faith in testimonials, I mean geez, what are they gonna do, put somebody's comment on there that says "your site sucked!"?

Nevertheless, it seemed more credible than most I looked at.
Thanks all! I'll be looking at each one of those...
