What kind of driving games are you looking to use it for?
If your goal is primarily MAME, then a force feedback wheel would be wasted, and probably not really worth the investment.
If you are looking at actual PC racers, then the Momo would be a great wheel, or if money is not a huge issue, then I'd suggest looking into the Logitech Driving Force Pro. It is sold as a PS2 wheel, but does work great for the PC as well.
