Welcome to the forum and thanks for asking our advice.
Bold subject line, eh? Let me qualify it down. I load for handgun only; 5 calibers, about 100-400 rounds per session and about 5,000-10,000 rounds a year. If this comes close to describing your situation, you might like to read on.
35 years after starting, I found I outgrew some gear and overbought elsewhere. So, I cleaned house. I emptied my bench and populated it with the best equipment I could find precisely fitting my loading needs. I could have saved a lot of experimentation and waste if I had known back then what I know now (about handloading and about myself).
Informed by my experience reconstituting my loading bench, I compiled a list of the barest essentials that would allow a novice loader to load well and which would still be gratifying in 30 years. (In my opinion and somewhat matching my style of shooting and loading.)
Here's a link to the thread that describes what I did.
I think it makes an ideal shopping list for the handloader just starting out. I hope you do, too.
For 5 calibers, $700 plus shipping to duplicate my entire current loading bench with all new stuff, misc accessories and tools. About $45 per caliber for extra dies and turrets. I am not in the least bit inconvenienced in my loading endeavors-no compromises.
