I loved my 550 for the longest time. The 650 is a step up from that. I need to stop looking at 1050's. They are even nicer. But for me, I can't use a bullet feeder because I shoot lead and my lead bullets are not "clean enough" from the lubing machine to ever expect them to work with a bullet feeder. So with out a bullet feeder I am personally convinced that a 1050 is no faster then a 650. For the life of me I can never seat the bullet before I am done pushing to prime. I am always done pushing to prime and I am still seating the bullet. I know the 1050 is nicer but it just wasn't worth the extra $600. 650 is darn near the perfect press.
