I also got the 6th WD Eldar codex and I haven't used it much, however at least It lasted a few years, not a few months. I'm to scared to buy any of the other books now. I'd been holding out for Chaos and thinking about picking up Space Wolves for farthers day. I guess there are just enough young/rich people out they that GW doesn't have to worry about us old rogue traders not buying books, for fear they will expire next week.
