I know some very knowledgeable techs who think very highly of SE cams. I've heard them remark that they perform well in the proper environment without objectionable side-effects, like valve noise and other woes after installing them. I wouldn't hesitate buying another one in the future, but I don't race my bike and just want it to perform at its best where I ride.
+2 on that. had a SE 103 w/255 cams upgrade done and using the SERT and i am quite happy with the power output. could i have got more with a different cam ? probably could have but for my riding 99% of the time its 2 up with the wife on it works for me.
