Is there really that big of a difference between S-Video and RGB on SNES?

[Zing]

I have official Sony PS2 component cables in their retail package that I would sell for $10 plus shipping if you, or anyone, is interested. I don't anticipate owning another PS2 in my lifetime.

I can't seem to find a decent a/b s-video switch box. I can find plenty of s-video only switches, but none with s-video and audio. If I have to have a separate switch for video and audio, I may as well just physically swap cables every time.

*edit* Actually, I managed to find one. http://studio1productions.com/switch-boxes.htm
