Ya, can't beat the free pricetag on uiFaces. Also if you click a face, it brings up different sizes you can use and also does rounded corners, etc. for you. Much nicer.
@rrhoover yup, saw uiFaces which reminded me about Facebox.
I actually like uiFaces more for use in mock avatars, because they seem like they actually are people's avatars (so they fit better when using them in this case).
