You'll only read about problems here, not successes. No one posts "I drove to work today and didn't get a CE light."
That said, Sube ABS is Sube ABS. I've had it successfully engage, and I've had it engage unnecessarily (IMHO). It is also possible that the TS will suffer from clutch shudder, if that's what you're referring to. I had a case of it a while back, but now in the coldest months it is a lot less apparent. Not bad enough to bother taking it to the dealer.
Test drive one and see if it exhibits the things you're looking for. I wouldn't hesitate to buy another Sube.
