I've been using the X-Box 360 Windows controller (around $30 at Best Buy or online) as my number two unit on sims for years... in FSX and here in AF2 it's my autopilot unit with buttons easily performing master on / off, HDG lock, HDG knobs, ALT, SPD, exterior lights, reverser axis, etc... It's great.... just a recommendation.... I fly with a normal Logitech joystick as all this tucks away great in my suitcase while flying for a living....
