Making a Saturn USB pad

[Pullmyfinger]

One of my saturn controllers died on me, everything seems fine but it just won't work, so I wanted to make it USB, using this tutorial.

It says to use an Elecom pad, but an amazon search brings me nothing. Has anyone done this? What controller did you use?

You can order one of these kits, I think that's what I'm going to do.
