Don't want to pick on your information thread and have nothing bad to say about Dillon at all but... what I'm seeing is a good write-up but one that I perceive predicated on a few false assumptions. One assumption being that the only justification and approach to reloading is your concept of a minimum volume and minimum investment. I'm sure your suggestions are great based on your needs but I could never justify that level of investment based on my needs. I can certainly afford it but why? I don't buy a 1-ton 4x4 pickup to fetch groceries either.

I am able to produce a reasonable volume (~500 pistol cartridges/hr, pre-prepped cases) on a single stage and a progressive for several calibers with substantially less investment. In good weather I shoot probably 2k-3K handguns loads and maybe half as much rifle per month. It may not be quite as fast or quite as easy but the ammo is every bit as good and candidly I'm not really trying to impress anybody but myself.

I don't assert my setup to be comparable however I do produce quality ammunition at a volume that is adequate for my needs. My entire setup with accessories and including materials to build the bench was under $1000.

The point I'm making is before you can make a determination or recommendation you should understand a potential reloader's needs, volume, budget and most importantly motivation. Not everyone reloads multiple calibers or in high volumes, some reload in the pursuit of their idea of a perfect round or may be restricted by income to a more laborious approach while others reload for cost savings or stockpiling ammunition in private, etc, ad nauseum.

I don't mean to discourage your write up just wanted to point out technique, tips, lessons learned might be more valuable than a particular opinion on equipment selection derived from a specific individual's requirements. The best tutorials aren't about what you think is right but imparting the knowledge for another to determine what is right for them based on your experience.
