I suspect that you'll get a lot of responses with as many reloaders as this forum has; this is my 2 cents:
Except for the dies and a shellholder, everything you will be buying is usable for other caliber reloading and is the entry cost into the game. It's like purchasing equipment in a manufacturing operation, major up front cost but long lived benefits.
I've gone through it all over 40+ years, starting with Lee hand dies at under $20 at the time. Each caliber has it's own set, then I used either a club or hammer to reload. Very slow but it worked and it was cheap. Powder measuring accomplished using the included and calibrated plastic spoon. To switch powder types from that which the kit was designed for, I bought the entire set of plastic spoons. Lots of downsides, like no way to tweak powder weight. So, I bought a cheap balance beam scale,the prices now are out of sight). The scale, which I still have and sits idle) was the major capital investment.
Then I wanted more speed, so I added an RCBS rockchucker. I still have it and still use it at times. I also needed new dies, and I purchased a hand powder trickler; all of which I still have and, for the first calibers I reloaded, are 30 years old. Then a kinetic bullet puller which I still use. After 20 years I wore out the first one and now have a new one. Along the way I picked up a Lee hand primer which I still use; simple and very effective. Then the electronic calipers and then the micrometer and case trimmer.
If you want to load for consistency and not take all night to load 10 rounds, here's the full up suite I would recommend:
Good single stage "O" press, like RCBS or Hornady or Lee. You will need to put some pressure on those cases and a "C" shaped press won't keep it's dimensions well.
Good Dies, Lee, Dillon, RCBS, Forster, Redding,I don't like Hornady dies)
A scale, electronics are faster than beams, prices can be around $100 but there may be some less expensive; look around or wait for another respondent with his/her list for you to look at.
You can do without a powder measure by throwing some powder into the scale and use the trickler to complete the weight; however this is pretty slow. RCBS and Redding, at least, make decent, repeatable, powder measures. Put this at the end of the list.
Electronic calipers are an important tool; unlike manual calipers, you can zero the caliper at any position and then measure items against that zero, such as when measuring for case length over/under a standard.
Micrometer can wait.
Stoney Point comparator turned out to be something I should have had long before I actually bought the set. Very useful for accurate bullet seating, shoulder setback before/after sizing, etc. Inexpensive, more important than micrometer.
Kinetic bullet puller, RCBS or equivalent is important, too.
Lee hand primer.
RCBS or Lyman case trimmer. Important for bottleneck cartridges like 30-06.
Loading block,plastic MTM is fine)
Primer pocket cleaner,and/or, upscale, primer pocket reamer).
Case mouth deburring tool,RCBS and others).
Primer hole deburring tool, nice but unless you're in competition, not necessary.
The big ticket items as I see them are the press and scale, followed by the powder measure then case trimmer.
A good press and scale will probably run $250-$275 unless you can find an inexpensive scale, then knock off $50 from above.
I hope this helps; now let's see what other folks use or recommend. Frankly, I'm interested, too since I don't know what others have been using.
At the moment, I'm using a Dillon 550B with RCBS chargemaster plus all the gage's and gimmicks I can get my hands on. Don't ask, and don't tell my wife!!
