Reloading can be a viable option; however, ...
From my perspective, with the amount of ammo that I can consume each month, I would NOT consider a single stage press. Prior to a month ago, all of my handgun ammo was produced on a Dillon 550B, and my rifle ammo on an older RCBS JR. Over time, they have paid for themselves. My first progressive press was a Dillon Square Deal B, purchased new for $198. I'm now doing a shift because I don't have the patience to do a primer assembly swap on the 550B.
I've recently purchased a new Dillon SDB in 45 ACP (LPP) and one in 9mm (SPP). Either machine can pump out about 300 rounds an hour, which means less time spent standing on my damaged legs. The problem was, neither machine sells for the original $198. The used 9mm SDB sold for about $450, and the new 45 SDB sold for a bit more than $700. Never factor in the price of your press, because if you take care of it, you'll get your money back if you sell it!
Even though I am working with components that were acquired a few years ago, I'd look at current component costs. Looking at 9mm exclusively:
Primers: $0.06-0.08 each
Powder: $0.04-0.06 per cartridge (depending on the load)
Cases: free, just save your brass!
Bullets (each): homemade cast: $0.05, purchased: $0.08-$0.10, plated: $0.08-0.10, FMJ: $0.10, JHP: $0.12+
Therefore, you could load a 50 round box for $7.50-13.00, depending on what you want. Only you can be the judge on whether you've saved money!
The $10,000 question is, will you save money? Possibly! However, what you can safely say is, as long as you have components, you WILL have ammo when supplies either dry up or becomes exorbitantly priced!
