Not to put too fine a point on things...
I think you are way out on the price of things,
And I can point out a couple of ways that might make things go easier.
1. If you are handy, you might want to check out case feeders, or even bullet feeders on YouTube
Case feeders in particular are easy to build from a 5 gallon bucket and a $10 motor off eBay.
Saves you over $250 from Dillon.
2. Switching dies and shell plates in a Dillon takes very little time.
Messing with the large to small primer can be a REAL pain in the butt.
Not just switching the hardware, but getting the primer ram tuned so it installs your particular choice in primers in your particular cases correctly.
Not all primers & cases are created equal..
I can pretty much guarantee you will be looking for small primer .45 cases, or holding off on loading .45s until you have a bunch to make that conversion worth while.
3. Dillon XL650 has come down, about $600 with shipping including a set of dies.
Watch eBay for caliber changes and upgrades to make conversions to other calibers a little cheaper.
4. I reload for a shooting club/group,
To lay off liability, EVERYONE sits in front of the machine and pulls the handle.
Everyone has signed disclaimers, and we have all been friends for 30 years,
And I'm still not totally comfortable,
As someone else mentioned, in the case the worst happens, parents, spouse, siblings and children can sue you into oblivion, even with signed disclaimers and shared liability...
You will probably win the law suit, but you will spend $250,000 doing it...
If you don't have signed disclaimers and shared liability, you don't have a chance.
