I recently decided to pick up these wonderful games, but I wanted to get a decent flight stick to use with them. All I have right now are two gravis xterminator gamepads (which are fine for other games, but just not right for flight combat sims).

Any suggestions?

I'm using a Gravis Blackhawk Digital over here. It's fairly old (possibly pre-2000), but it works fine, and offers even more interactivity than XWA technically needs (the fourway cap-button is useless, as is the second-finger trigger, and I get more use out of the game's -/F9/F10/+ presets than the stick's built-in throttle wheel).

It's plenty sturdy for me too, but I tend to be a light hand.

Personally I have a nice original non-force feedback sidewinder,got me down the death star and back out again XD
