Graham, good luck with the XBOX.
And for the record, I have six sons, and three PS3's in the house.
None of them are mine, but I am allowed play time.
I just can't see purchasing a wheel, as the "Good Wheel" for GT3, not only was expensive, but not compatible with GT4.
It was at that point that I decided, that no matter how much better the gameplay was, I was sticking to the DS2 or DS3.
Add to that I had a wheel at one time that I recieved as a gift.
I had to be adjusted and calibrated often.
I decided that I'd rather play than spend time calibrating the wheel.
Especially as it seemed to need calibrating all the time.
