I use a Lyman DPS and like it. It changed the way I load. I don't have a need for a progressive, but load cartridges on a Lee turret. I can push for a 45 gr load, size deprime, prime and fill the case then push for a new powder drop. I seat the bullet start over and the powder is ready before I am. It doesn't work if you have a primed case fill it, grab another case and want to pour powder right away.

If however you really want to load 50 on a loading block, you can prime a lubed case, wipe it down and load powder then prep the next case while it is dispensing powder.

Benchrest shooters believe the consistency of the powder charge within a grain is not even in the top ten when it comes to accuracy.
