I have this pad for my PC
http://www.cybersnipa.com/us/gaming-keyboards/gamepad.php
but I often simply use mouse and keyboard.
For driving games I bought first a Thrustmaster Universal Challenge wheel: DON'T EVER BUY IT! IT'S UTTER SHIT! The gear down lever broke twice, it's too fragile for fast changing down, unless you are an utterly calm person and able to perfectly husband your force even in frantic moments. The first time I could fix it with superglue, but shortly after it broke in a different place, thinner, so the fix won't last. And it's very difficult to have breakings covered by warranty. There are enough buttons on it to replace the function, but it's uncomfortable for difficult games and racetracks.
Now I've got a Trust GM-3500R with Force Feedback, I still have to try it, but it looks a lot more robust, its only visible drawback is the less practical position of the HAT switch, but I don't use it often in racing games.
For flying sims I first got a MS Sidewinder Precision Pro, it had a feature, doubling function for its base buttons, that I still miss, but it broke a week after its warranty expired. Now I've had a Logitech Wingman Extreme Digital 3D for many years, it still works fine.
