I got one. I haven't tried Mario Kart yet (need time). I enjoy it with F-Zero, but while it makes the game more "challening," the experience is more engaging to me. Your possible enjoyment with F-zero will depend on finding a button scheme you're comfortable with, because the only practicall way of holding it is a 9o'clock-3o'clock position. And you have to adjust angular sensitivity. Figuring out where you want Gas and the L/R slides is the problem.
Burnout 2: IT JUST RULES. Button scheme, handling, force feedback feel great with it -- especially in the First-person view. If you've got a decently sized TV and a good seating arrangement (one ideal for driving), it might make you forget about arcade racers.
