The Lee Safety Prime as used on the Lee Classic Turret and the Lee Classic Cast Single Stage and Challenger Single Stage presses is a HUGE advance over the priming system on the Pro-1000 (which I have used) and the Loadmaster (which I have not used).
The Safety prime is manually operated, but keeps the primers up and above the debris from spent primers and allows you to easily see the primer when it is dropped into the primer cup.
Sadly, this does not help you much unless you might consider the Lee Classic Turret (which is what I switched to when I decided I did not like fussing with my Pro-1000 presses). I am much happier now. But that is my loading style and quantity needs, not yours.
