If you must have FF, then either the Act Labs or the Guillemot Ferrari take the top prize.
If FF is not necessary (and you have plenty of money), the Thomas SuperWheel is super sweet.

Not for me it didn't. In fact, I've set my best times to date in Grand Prix Legends with my Ferrari wheel. I also did not suffer any major CPU "hit" either, but I think that's mainly a problem with just the Micro$oft FF wheels.
