I had this guy tell me that the 601, 602, 603 motors are junk and the 617 are the best ever. He asked me if I saw a 601, 602, 603 motor with 1 million miles? He said that he has only seen a 617 with 1 million miles. My question is, has anyone ever seen or have 1 million miles on there 60x motor? This guy was making me mad! I know that the 60x motors are not junk. So lets hear it guys, have you?
