WTB: PSX to Saturn converter

I am looking for a converter that allows a Playstation controller to be used on the Saturn like the one Play-Asia was selling. Send me a PM if you have one (or two) and what condition it is in.

I don't have one for sale, but they do:

Personally, I would love an adapter that goes the other way around so I could have Saturn pad goodness on my PS2.

Thanks Gohan, I found it listed at three other places but it was out of stock. I am getting a multi-system Jammacast that uses PS2 controllers. I have converters for Xbox and Dreamcast controllers. I would like to play some Saturn games with it as well - like Guardian Heroes and some shmups.
