Some will bad mouth that press because the base is not cast iron. But I have one like that and have reloaded thousands upon thousands of rounds from 9mm through 30-06, sized unknown number of bullets, and did everything on that press any knowledgeable reloader should do. No the press ain't "weak" and no there are no "variations" in my reloads from a "sloppy" press. I will admit the used primer disposal was a concern when I first got my press, but that was quickly remedied. I mounted my press on a Rock Dock and drilled a 2" hole in the mounting plate. On occasion I would remove the press from the dock and shake it over my scrap bucket. "Problem" solved...
