personally I prefer doing hair in post work ( I always use a mouse ) the post work doos (here in free stuff) are a good start if you don't want to start from scratch... but if you're doing animations, then hair models with textures and transparencies is the way to go...Anton (http://www.bbay.com/anton) has several, Jim Burton (http://www.zygote.com) has a nice pack, and there are tons of freebies out there...
