If you go for one of those, especially the Mihai hair, I recommend running the .obj file through a program called STOMP. It defrags the file so that it renders easier and doesn't get hung up.

STOMP

You can read more about it here and get a brief tutorial on how to use it. It's really, really easy

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
