There is a nice compromise between a single stage and progressive. The Lee classic turret press will load close to three times faster than a SS and half of a Dillon 550. If 175 to200 rounds per hour will meet your needs then you might want to take a look at the CT. The only thing I don't like about the Dillon square deal is the proprietary dies. I would save for the 550 if you think you reload rifle at some point down the road.
I don't ever remember being absent minded.
