Has anyone used the ScanAlert.com service?

["Lachniet, Mark" <mlachniet () sequoianet com>]

Hello all,

Does anyone have any experience with the ScanAlert.com vulnerability
assessment service?

At http://www.scanalert.com/Content.sa?sec=4&sub=2 they offer payment
card industry (PCI) certification for $149/year for 6 hosts. 

I'm wondering if anyone has used them, and any comments good, bad or
indifferent.  

Thanks,

Mark Lachniet
