650 is the best press I've ever owned ( I've had four different types)
I load 16 diff. calibers, don't buy a powder measure for each toolhead, I use 1 with a small bar and 1 with a large bar. I also use the auto primer tube filling station, it takes a little getting used to but works fine.
I have 950 reloaded once fired .223 with mixed headstamps in a 50 cal tin with 55 grain boattails, 27 grain 748 winchester powder, loaded with a dillon 650 with powder check ( no squibs or doubles) $350 This ammo loaded by a FFL license to manufacture ammo, sets up at gun shows to sell.
