There are very few third party wheels for the XBox360 that aren't crap. So get the official Microsoft one. I haven't used it myself, but I've heard good things about it. No stick shift, just paddle shifters.
The Porsche race wheel for the XBox360 is really the only other option, but it's probably out of your price range. It's almost $200 for the wheel alone, without the shifter or pedals.
