Aside from the one that came with the original Apollo, the updated version wasn't released.

BUT, pdxjims had a few that were available from OKCRandy's forums. Not certain if they're still available, but you could contact Randy via his store and find out.

And paganeagle had a "superhero suit" for Apollo made from pdxjim's bodysuit, too. He had it at his site; there might still be a link from the main Apollo page.
