You're going to need:
Load manuals. Preferably more than one.
Press - either one will last, I prefer RCBS or Redding, but that's a personal choice.
Dies and shell holder--I just got a Redding Deluxe three die set for my B'day!
Case trimmer- Again, look and see. You can get by with a Lee for years, but I ended up with an RCBS, my son has a Redding.
Chamfer and deburr tool.
Scale - I bought a Pact BBK-II electronic scale. There again, the balance beam scales are ok, people have been using them for years.
Calipers, so you'll know what size your brass is. Kinda handy if you don't want bad things to happen.
Powder Measure --Again,, I have an RCBS, but really don't use it too much, unless I'm loading with ball powder. Most of the time I use Lee dippers, and weigh each charge.
Case lube- Something to clean and lube the inside of the case necks, and a way to lube the outsides. I like Imperial sizing die wax.
A tumbler is good to have. Clean brass is easier to inspect.
A loading block is nice to have, too.
RCBS makes a nice hand priming tool that uses the same shell holder that goes in the press, and I think the newer one doesn't need a shell holder... but you'd have to check on that one, I may be wrong.
I'm probably forgetting something, but if I am, someone else will chime in..
