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.
