I pieced mine together. I started with an RCBS Rock Chucker, 505 scale and a couple of loading manuals. All of which I still use, except the manuals, they have been upgraded with newer ones. I used the arm on the press to prime my cases for years. I have since gotten a priming tool. That was back before the internet, now you could get by without the loading manuals, and look every thing up on the internet, including how to reload, just make sure you use reliable data. I am a little old school and I like using the books, there is a lot of information there and I can look things up very quickly and I do not have to rely on the internet being up. But you can get by without them to save money. You can then add pieces as you go, to make it easier. You will need to add a case trimmer, I used the Lee type to start with. I have powered tools now that I used to use by hand. I have a powered case trimmer, a powered powder thrower a powered case prep center, etc. You do not need these things, they make your "chore" easier however. My biggest advice is buy something once. Do not buy and have to replace later or upgrade, that costs you more in the long run. I cannot remember how much I paid for the Rock Chucker, but if I remember, it seemed steep at the time, but I am still using it to load every case I have.
Good Luck and Good Shooting
