You'd be supprised. I have about 50 sets of TV or movie's with various 'other' cases. The Planet of the Apes full complete with the monkey head, the Family GUy with Stewie's head as the case... so on and so forth.
well i picked up the metal case first at fye. didnt knew that had them so i went hey what ever. then i found out about the different cases. personally i wanted the one at costco b/c of the bobble heads
