My wife bought me a Lee Anniversary kit that included the manual "modern reloading by Richard Lee" in the early-mid 1990s,
The only other things I had to buy were dies and case length gauges (to trim cases) for each caliber I wanted to reload and of course consumables (powder, bullets, primers).
Though I have added a few pieces since then, everything that came in the kit still works and loads very good ammo.
After reading the manual up to the part that contains the load data load data twice (not nearly as much reading as you would think looking at the thickness of the book which is mostly load data) I kept it handy for reference and started loading.
It's a really decent setup to start and learn on and everything you need to start with one caliber can be had for under $200
