A single stage press is a very good way to start. Unfortunately, a reloader will outgrow it if they want to reload pistol ammo often. I tried reloading 9mm on a single stage press but it got to be too time consuming and not worth the time put in, especially considering that 9mm was only $5-6 a box at the time.

I would start with a cheap press such as a lee challenger so that you don't have too much money stuck into it- the press is more than enough needed to reload pistol rounds- no need to spend $100 on a single stage press here. Learn the process, work up a few loads, determine how much you are going to shoot. If you ar eonly going to shoot a few hundred a year, the single stage press will probably serve your needs. If you are going to shoot alot, you'll want to move up to a Lee or Dillon progressive. The Dillon is much more expensive but will work very nicely right out of the box, the Lee will take some tinkering and adjustment, but will do the same job for a fraction of the cost.

As mentioned above, Unique works well for the .45, as does WW231 and Bullseye.
