I have really wanted to get back into warhammer after having taken a couple year break. I used to play skaven, but have been drawn to starting up a beastmen army.

Since I don't like playing a grey horde it will take a while for me to get an army painted to a decent standard, so it will be in a good position when the new army book finally arrives. My main question is what units should I buy? Right now I'm thinking getting a couple beast herds. Other then that are there any units worth getting now?
