Hi. We threw some ideas about regarding the Tau fleet long before it was released. Also, obviously, that meant that there were no minis. So, one of the guys put some together using
40K Crisis suits:

Forge World also make a fleet for the Tau using models derived from the Fire Warrior
FPS game. They are in the
BFG section of their site and are very nice.
