ask a million people and get totaly confused with the differant answers you will get.
For starting you should get a kit consisting of a single stage press, scale, powder throw, dies,lube pad, lube, primer tool and a load data book. This is the minimum, all of the companys offer these kits.
You will also want a differant load manual book read both and confirm your load, at least 1 loading block, a trimmer, chamfer tool, primer pocket cleaner and calipers. A case cleaner is nice but not a must.
After a while (2 or 3 years) you may want to get a progressive setup for pistol by then you will know what brand and type you need.
