You don't want to hear this probably, but I think you are going to find out that there is no such thing as the perfect setup....don't care what your budget is.
Gaston Glock thinks he makes a perfect gun, Steve Jobs thinks he makes a perfect computer, and the Dillon folks think they make perfect loading tools. Sorry, no such thing.
What you are going to find is that no matter what press or other tools you buy, you will have to put up with weaknesses, failures and problems. You'll have to come up with work-a-rounds, temporary tweaks, and your equipment will require a certain & consistant amount of TLC to keep it all running in top form. Yet its not at all a bleak situation, because we don't have to have perfect tools to load great (albeit not perfect) ammo, and to love nearly every minute of it. It's more than worth while and is a source of great fun for almost all of us.
You pay more for quality, and top of the line quality is sometimes the best answer...but it's not always. Depends on an individual's means, tastes, needs, habits, and certainly his point of view.
For example, people say Sinclair's hand primer is the best there is....yet, it loads only one primer at a time. I personally prefer RCBS's APS strip primers, bench-mounted or the hand version. While the Sinclair is a bench rest shooter's delight (and status symbol) on any range, I don't think one at a time is the best answer for most of us.
Another example: Dillon's 1050 press is hands down the best press out there. But if you want to load 8 calibers often and you can't afford 8 1050's, perhaps a quicker changing Hornady AP or RCBS Pro 2000 may be more "perfect".... No...perfect's not the right word...more useful for you.
I know you're looking for specifics, but I can only give specifics for what I do from my point of view. Same with every other answer you get in this thread. I've been playing in this hobby for 40 years, but the progressive press bug only hit 3 years ago. So from my view....
Here's what I like, (beyond the RCBS APS primer system): Lyman 2500 Tumblers with 20/40 Corn Cob & Dillon Polish, Powered Forster Trimmer with 3-way cutter, (Giraud is very nice for others, but my arthritic hands say no), Hornady Pistol Bullet Feeder, RCBS Rifle Bullet Feeder. Those are more trouble-free than Hornady's Case Feeders. I'm liking Lee or RCBS pistol dies just fine. RCBS and Forster Rifle dies. RCBS 10/10 beam scale. RCBS Chargemaster electronic scale/trickler. Dillon 500 Swager. RCBS Trim Mate, or Lyman's version if you have room for it.........and I like
my torsion beam style of bench building. Perfect? Nah, but close enough for me.
