Monster Cable GCGL300 SV-10 GameCube S-Video A/V Cable (10 Feet)
S Video is good
I am mostly writing this to correct a comment made in the previous review. S-Video does not enable progressive scan output, only component video allows that. The Gamecube component video cable is only available through nintendo's website. Aside from that, this is the best way to hook up your gamecube!
