The figure's original price was $60 initially, but damn did it go up. And yes, her breast size is bigger on the figure. Only slightly bigger though, I think her Chrono Phantasma artwork is by far the largest she's gotten. And Symm, that little thing is cute.

If I knew where to get them, I'd tell you, but the doll is new to me.
Edit: And it really helps if you have a friend that has THREE COPIES of the same damn figurine. Calling him a Makoto fanatic would be an understatement. He practically worships her. His room is in her colors, and has "MAKOTO" written all over the place, ranging from 5 different arcade sticks, posters galore, custom furnishings, and all sorts of amazing crap.
...I shined a blacklight on the figure I bought off him, just in case. It's clean. (thank goodness)
