I checked it out and it looks like its pretty well set up. Have you checked out the ISSA? They offer a lot more programs and you do not have to pay a membership fee to stay certified, but you do have to continue with you education and take a different cert package every couple years, and I would rather pay for more education, than just pay to keep my cert. After you add in all the extra costs of the NFPT, the ISSA isn't that much more expensive. I think their addy is www.issaonline.com
I got my cert through them, and was extremely happy with the course and what I learned. Later
