>>5858864Your only options are Super Action Statues and Real Action Heroes as far as I know.
SAS has three different colorways of Part 3 Jotaro, though none are particularly notable figures. They also made Part 4 Jotaro, who's a bit of a better figure.
RAH made both Part 3 and Part 6 Jotaro. They're really nice figures, though both are gonna be super expensive.
