...Does it really make that much of a difference? Only racing games I have are F-Zero GX and Mario Kart Double Dash!!, and I was wondering if it would be worth getting for those games alone (I don't plan on getting any more for GameCube)

I've used the Gran Turismo Wheel, is it the same as that... that one was VERY nice.

Edit: Does anyone know if Xbox has a Licensed Wheel? ...that's good. (Burnout 3 and PGR 2)
