Joystick Directory at Joystick Review. No one seems to be playing flight simulators anymore, so the reviews I’ve seen of joysticks are usually a couple of years old.
Microsoft has even exited the business, although ebay has quite a few SideWinder “Force Feedback 2”:http://www.joystickreview.com/microsoft/sidewinderforcefeedback2.asp’s around. Thye have a great rating of 89.5 out of 100.
Thrustmaster (now acquired by Guillemet) traditionally makes the most realistic joysticks. The most accurate current model is called the HOTAS Cougar at at $250 according to “Pricegrabber”:http://www.pricegrabber.com/search_getprod.php/masterid=5582218/search=thrustmaster it had better be incredible.
The “Top Gun Fox 2 Pro”:http://www.joystickreview.com/thrustmaster/topgunfox2projoystick.asp is still around and was super highly rated at 92.5 out of 100 and its a very reasonable “$35”:http://www.pricegrabber.com/search_getprod.php/masterid=5582213.
Finally there is the Saitek “X45”:http://www.joystickreview.com/saitke/x45digitaljoystickandthrottle.asp which is way overboard for the hard core gamer. Comes with both a throttle and a stick. At $77, its very complicated and really for the hard core gamer.
