Hello, I know from the forums that I have read on RCU most people prefer saito but I like OS. I have a saito 91 and a OS 91 I like the OS because I never touch the needles. It runs great every time on the other hand the saito took about half the summer to get adjusted. Now it runs good also I have a 65 that is three years old and had to replace the bearings.This is my opinion and Iam sure the saito guys have favorable opinions as well and I respect that.
