I started with a 650 about a year ago and couldn't be happier! I got the Dillon setup video which made setup easier. I went back and fourth between the 550/650, I would have been disappointed if I had not gone for the 650 right out of the gate. The 650 is an outstanding machine, I was cranking out good ammo right away! Start slow and don't worry about speed and you will do just fine.
