Okay; I'm asking this question a little late as I've already done my implementation and made my choices.
Still; It seemed to me the most secure form of authentication for my small ~100 user wireless network was EAP-TLS. My requirements needed me to simply authenticate the machine to the network so a simple certificate based authentication using the same for the encryption seemed the best route. Also the others seemed to have less actual security in them from what I read.
What other options are there that might be simple and rely on a user/pass combination rather than the certificate and are they truely better?
My boss really liked the certificate method as it gave us what he felt was hard controls.
Of course the cert management is a bit of a pain...
