Which O/S are you running? For XP a well tried and tested force -feedback stick is the Microsoft Sidewinder 2 (USB version) - not made any more but there are quite a few available on ebay. I've had one for about 5 years but I don't think they work on Windows Vista though (no drivers?)
Definitely don't pay the £99 some of the sellers are asking - they weren't that expensive when they were new!
Unless you're looking for a new one, a proper lookking yoke or something more sophisticated.
