Hi Jeaostro,
First of, I represent Secunia and so I'm probably biased - So I won't comment on the usability of the CSI.
However, we would be happy to help you obtain one of our free trials, so you can try out the product before making a final decision.
If you go here, http://secunia.com/vulnerability_scanning/corporate/trial/ and enter "www.windows-noob.com" as the reference code in the trial form, you will instantly be given a username and password. Upon request, the free trial can be extended to 30 days.
Hope this helps,
Emil Petersen,
Secunia support.
