I like to play with Flight Simulator while on trips, but since version 2002, it requires a joystick (keyboard commands don't cut it). I certainly don't want to carry my full-size joystick with me. Are there any miniature joysticks available for use in these circumstances.

I have an IBM T-40 with a pointing stick mouse and a touch pad, but I can't figure out a way to use either of those as a joystick.
