I studied this extensively before I purchased my first progressive press. Was on a limited budget and could not buy the Dillon. I chose the Lee Loadmaster knowing full well that tinkering would be in the formula. I happen to be very mechanically inclined and like to improve things, so that was not a problem.
I still want a Dillon 550b, but after some tinkering I've got this Lee cranking out ammo for our pistols.
