I currently run a One Stop Slot Shop OS3 controller in my HO racing. But I've borrowed Ttuspeed BPIIs to try before and I think I actually drove slightly better with them.

I'm ordering one next week for my son to use (he currently runs a DS3) but might spring for my own as well! 

Really nice controllers and I think the price is incredibly reasonable for what you get. All of that additional tuning compared to the DS3 for barely double the price seems pretty reasonable.
