[Blind-sysadmins] DoD 8570 Security Certs

I have a need to get baseline certified for DoD 8570. Initially, I was thinking about doing the CompTIA Security Plus-it is quick, cheap, etc. The CISSP would get me level 3 certified though and has better long-term viability. I would like to hear anyone's experiences studying for and then taking the tests for either of these certifications. Thank you, Matt
