FSX is the latest from Microsoft however some can contend on greatest...

You can buy FSX at your local Best Buy, Frys, Gamestop, Target, ect. Might have luck at Gamestop.

If this is just for procedures, I wouldn't spend too much on a yoke. A simple logitech joystick should do.

If you decide to buy a yoke and throttle, the lower cost option would be the Saitek combo.
