OP.. depends.. is this your first go at reloading?.. do you expect to load 1000s of rounds?
I got into it primarily for M1 Garand loads as those can be tough to find, but use it for my 30-06 hunting rifle, as well as for 9mm in times of scarce supply. I don't shoot a ton of rounds so doing 50-100 at a time doesn't bother me.
I have the Hornady LnL classic kit which will have most stuff to get you started for reasonable money...

then you can replace/add things you think you want/need. Tumbler, calipers, accessories, etc.
