Broken on the NG forums was making some, or at least gauging interest. I prepaid for (and received) an SNES RGB cable from him a while back and it works perfectly. Nice guy too.
My Saturn cable I bought from the gal in Florida, but man her customer service is shit. Good cables but I hate to recommend her. She disappears from ebay for stretches of time, so you may have better luck ordering from her website (retro-access.com I think) if you want to go that route.
GL man!
Edit: nvm, her website is down. You may also try retrogamingcables.com. He ships to the US and is also friendly to deal with.
