I buy a wheel stand pro one & half years ago,used with G25.
Basically it's ok even set the FFB to ten in GT5p.
Very stable when drive smoothly ,no mistake, no seriously spin,
even when drifting.
But once the car lost control and try to correct the direction in quick,
mostly pull up the whole set wheel with stand.
Maybe just my handling problem.
Finally, I changed to AP2 one month before GT5 release.
AP2 price little higher then wsp, I get wsp $1600 HKD, AP2 $1800 HKD,
both with shifter mount, around $25 USD different.
After all I found that the AP2 not much bigger then wsp in size.
Used up almost the same space, but AP2 far more stable then wsp,
and I can add a reversed pedal mount by myself.
Anyway ,wsp still a good choice (I passed it to my brother~

)
