I have a PS2, Gamecube, and XBOX, so I think I solved one of the problems I have been comtemplating for efficient game audio/video switching. My plan is to use a regular composite video RCA switch for the component video cables, and use this optical audio switch for the sound. It is partsexpress.com part # 180-980 which is only $19.80. Just a recommendation for anyone who is looking for this kind of setup. Part at partsexpess.com link BYW, Let me know if you know a better solution for under $50.
