I would say that budget rules what gear people get when they start out. I would stay away from the single stage press for pistols, as it is painfully slow. I only single stage load my bolt rifle loads, and this is only 20 or so rounds at a time. Pistol rounds, you are going to need a higher volume of rounds produced in a shorter period of time. Nobody has all day to produce a couple hundred rounds.
I got a used Dillon years ago for about $500 and it paid for itself in a very short period of time. A few hundred rounds can be produced easily in an hour.
But cost wise, Hornady and other presses are cheaper in price and can most likely give you the same result.
One thing you will want to get is carbide dies. No lubing, cases don't get stuck and they last forever.
If i'm not mistaken, most presses will come with a set of dies these days, so you can buy a press and have your 9mm dies ready to go.
I use titegroup powder, and it gives me roughly 1700 rounds per pound of powder. It goes a long way, and its about $26 per lb.
Shop around for a progressive, and look for deals or sales.
