S-Video Cable for Supernova?

I recently got a used Mas Supernova, that I finally fixed the broken power switch on (wooohooooo, I soldered something successfully lol ) and the regular a/v cables make the screen too wavy. It didn't come with an S-Video cable, problem is the jack on the Supernova doesn't fit a regular S-Video cable. Anyone know where I can get an S-Video cable that is compatible with the Supernova?

Im sure you can order it from mas themselves?

If they charge too much, or if you are feeling creative, you can build one also.
