I have never had an issue with RCBS or MEC. In fact, several years ago I bought a MEC 8983 that a guy had problems with and had literally thrown the parts in a cardboard box and had it out at a yard sale. It was brand new. I bought it and tried to put it back together and was out of my depth with the thing. Called MEC Customer Service, explained the problem and the guy on the other end spent a solid hour with me and stepped me through the reconstruction process. It works great and I am even more than ever a MEC customer.
