What do use to play racing games? Wheel? What brand?
I'm a wheel guy myself with the Logitech Driving Force Pro. There's not a better PS2 wheel out there. Kinda pricey, but if you love racing games, you'll love the wheel.
There was a time not too long ago that I was real comfortable with that dual shock in my hands (except that my thumb hurt like heck!), but after spending alot of time getting used to the DFP, I can't even hardly drive with that DS anymore. The wheel doesn't automatically make you a better racer, but there are lots of turns that you can make alot easier with the wheel and the pedals make it alot easier to feather the throttle and pump the brake when needed.
Get the wheel!!
