If I recall correctly, I didn't want to spend much money at the time, since the idea was to reload in order to save money, so I got the most basic thing. Each single step requires grabbing a case from the pile (or the tray), putting it in the collar, pulling the handle to do the motion, then removing the case and putting it in the tray (or box). The handle angle can be adjusted, and it can be set up for left-handed by reversing the handle and moving one of the support pins (the 3 pins between the base and top plate).
Here's the basic mechanism, fitted with the de-priming attachment and collar (at the top of the post that moves up through the middle). Each pull drives the brass upward so a hardened pin at the top will pop the primer out. They get everywhere, so I usually do that step in the garage. My thumb is holding it down -- normally you bolt it to a workbench.
Here's the handheld primer (way faster and easier than using the big device):
Here's the main thing fitted for powder filling. Each pull-down of the handle forces that little disk back and forth once, dumping what's in the little center hole then returning under the cup to get refilled. It's all done by volume, so swapping the disks around is how you vary the amount of powder needed.
The here's the little rack you store the cases in between filling with powder and filling with a bullet.
What's not shown is a bullet setter and bullet crimper. Some folks who reload actually skip the "crimping" step since the bullets are usually in there good enough after the initial setter push (it crimps a little, but a crimper dies REALLY tightens it down). There's some voodoo in reloading circles about crimping allowing the powder to build up more pressure before the bullet flies, thereby giving you more speed and a flatter trajectory. I don't buy into that. Plus it's extra work.
I got this like 20 years ago, so no idea what they go for now, but my advice is to not bother with those fancy things that do everything like a factory line. You''l spend way more money, and they're not THAT much faster. Anyway, if you can find one of these and want my 9mm or 44 special die set, they're yours for the asking -- I never use them and all I have are 45ACP anyway now that I've sold and gifted all the 9mm pistols I had.
