I used to use a Logitech Rumblepad 2 for controlling EQMOD, Logitech have wired as well as wireless on the market.

If you get the XBOX controller working, I would be interested in seeing how to connect it also, sounds like a good alternative if the other controllers are unavailable or too expensive..
