Wendy,
If your goal is 100/hr. You can do that on the WAY cheaper than $500...
Lee 'Classic Turret' press.
Doesn't matter if it's the 3 hole or 4 hole tool head version.
I avoid Loadmaster or 'Pro' machines like the plague.
This is my favorite Lee 'Slow' press, and for $70-$80 this is hard to beat.
This is the press I use most outside of my Dillon production presses.
The DIRT CHEAP quick change tool heads get a workout decapping rounds, universal decapper, tearing down questionable rounds (didn't pass QC), along with banging out the occasional small batch oddball caliber rounds I don't want to set up & tune the Dillon for (usually 100 rounds or less, or calibers I only knock 100 rounds out every couple years)

I don't like any of Lee AUTO indexing presses, inaccurate when they do run, break often.
Besides the tool heads (Cheap) there is nothing at all proprietary about this press, common dies work just fine, so do common shell holders, and once adjusted in the tool head, no more die adjustments unless something wears!
Tool head changes are 5 seconds for caliber changes.
A flick of the wrist allows die changes... From sizing to seating to factory crimp die (if you use one).
3 holes are enough for 99% of what home reloaders do anyway, so 4th & 5th holes are wasted anyway.
With seater/crimp die you can run a powder thrower in the tool head, but I like more control over primer seating than any of the Lee machines offer...
I deprime/resize, then install primer manually (hand prime tool) and while I have the case in my hand, just go ahead and charge (powder) the case, back into the loading block waiting it's turn at the press.
The deal with powder dropper on a progressive press, you need TWO holes, one for the powder dropper AND one for the powder checker! If you run progressive, you MUST have an open hole for powder inspection! Just too easy to get under/over charge!
------
Although I know you hate the price of Dillon, it's actually worth the money up front, before you tool up for more common machines!
While Dillon makes you cry once, it works from there on out, and is pretty easily adjusted for ANYTHING you are doing from that point forward.
Keep in mind the replacement parts are FREE, Dillon has a 100% NO B.S. guarantee, and trust me, I've called them on it!
Buy once, cry once.
While Dillon will support some common dies, Dillon dies work remarkably well,
Everything else on a Dillon is proprietary, but I believe everything but the case feeder is covered under warranty... They have replace my dies, and more than once...
What I might suggest for the 'In Between' is the Dillon SBD (Square Deal B) package.
Comes in around your price range and does about every pistol caliber round GREAT.
There are a couple aftermarket (haven't used them) kits that allow for .223 but I'd be hesitant to screw one of them onto an SBS since it works so well with pistol rounds, and it has a lot of parts that have to be swapped over...
About all my pistol rounds are cranked out on an SBD, it's just so fast & easy to use and just kicks the crap out of all the other progressive loaders! I don't load but a few thousand pistol a year, but this is the machine to have if you go through a bunch of 9mm or .45 ACP (hard to hold cases).
Works great on rimmed rounds also, easy to change tool heads, primer swap takes a little effort, but not nearly what a 550 or 650 does!
The Dillon Case feeder is $250 which leaves you butthurt, but it's darn handy!
I build case feeders out of 5 gal. Buckets & grill motors or $15 eBay gear motors and they work pretty good. Don't know how handy at 'Tinkering' you are, but it's a $40-$50 alternative you might consider.
