The Microsoft Precision Pro works well - it configures automatically for FS2000 and is USB and serial (adaptor). Also it has a twisty stick so you can use the rudder. Cost about £40 I think. I had a Saitek Cyborg 3D before which was good too but the trigger is a bit too delicate if you're trying to blast anything and get a bit too involved.
