I am considering taking the giant leap for me and getting a progressive press. I have heard nothing but good about Dillion from a number of users but have heard good arguments regarding whether I should go with a 550 or a 650. I do not intend on ever needing to go super razoo with auto feeders, etc. and am happy with putting out a couple hundred an hour. I have heard that with a 650 there is no backing up if you have an error, while with the 550 you can back up and correct the problem without going through a complete cycle. As with any purchase I make I always consider quality and Dillions no B.S. warranty impresses me. Any input will be appreciated.
