Its good to know about the Gates belt, I had severe vibration at higher spindle speeds ( not all due to the belt) I went to the Fenner link belt, it was a bit noisy at first but did quiet down after a time.
I have the series 3 and am happy with it.

The best I could do was 3,500. Now, 5,000 RPM is no problem.
