I use a Gamecard Auto III, with a CH F-16 Combatstick and it works pretty well. I get a bit of jitter on the throttle, but the stick is very smooth. Works better than the soundcard gameport.
(Beware of the PDPI card. It doesn't work with CH drivers. There is a "workaround", but I never could make it work around. Gave the card away after wasting WAY too much time on it.)
