I already claimed one, but there really should be enough for everyone who wants one.
I know my characters each seemed to have their own. (Whether they wanted one or not, really.) So if they all took theirs with them when they came to live with me, then I should have about... 40+ rocket boards kicking around here somewhere. And approximately eighteen bajillion flying discs. Cool.

not looking for my team teleporter flyer, I swear.
