I just recently got one. I have it set up on a Lyman "C" press. Seems to work good. I was using an RCBS swage. I bought the Lee unit, on sale at Grafs. I think it works smoother than the RCBS swage. So far no complaints. I wouldn't set up any swage unit on anything but a cast iron press, because of the pressure, you put on the press when you swage.
