THIS might work. Anything cheap with a USB plug will do. Hit the Goodwill and the like.

I'm guessing it's this flightstick? This Logitech Extreme 3D Pro looks pretty attractive too, for $12 more.

Flightstick sounds like a pretty awesome upgrade... may have to give this a shot.

I used this when I replayed the older SW flight sims recently. Worked well.
