Are you talking about one that actually functions or a poser model?
I have the large (poser) one from Autoform. When I first installed it I was unhappy with the way it looked - too fake and non-functional looking. So I took it off and spent 2 weeks modifying the front, installed a real screen, etc. so that it looks real. Click on my avatar (I know, it's not a close-up shot but I think it looks cool). I haven't taken any detailed photos of how I modified it. I think they make a smaller one as well.
