I'm having some people over this weekend, and was thinking of getting Spy Kids 3-D for the novelty of it. However, it only comes with 4 pair of 3-D glasses, and I would need 6. Does anyone have any recommendations for where and how to get an additional 2 pair? Also, I'm not aware of any other 3-D films available currently on DVD save for Nightmare on Elm Street and a set that purportedly does not work on a progressive scan player. Anyone have any suggestions?
