I have been looking at getting a set of bearings for my O.S. 81 VR-M and,WOW, what a variety of prices. BOCA comes in highest and at the other end is RCBearings.com. I have learned in the past that you usually get what you pay for but have to ask, Has any-one had experience with rcbearings.com. I am looking at getting the ceramic bearings because of the marine app and have heard they are the way to go. Any input??
