Dude, could have just ask me, the updates are pretty dated now, like before 6th ed. had been released (except for the Vehicle update, still old though).
Anyhow, yeah they are pretty cheap in terms of point; if it weren't for the price tag the tetras are what every Tau player would be using in every game.
I'm holding back on investing anything until either Tau flyers come (which I'll get three if the rules are good, one if not) or when the codex releases.
