http://www.pcpilot.net which does a subscription only magazine has just done a review of controllers. Best non force feedback was the logitech wingman extreme digital 3d, best valueforce feedback was MS force-feedback pro, which I use, best overall was CH force fx (costs a bit and you need a throttle) GBP130. In the past I have used a logic 3 (blue in colour) which was very good but no rudder. Unfortunately the better ones do cost.
