Tell him to buy a LCT. You can easily produce 150 rounds an hour. If he's not shooting thousands a month this is more than enough production.
If he really wants a progressive then save enough for a Dillon. This is a case of buy once, cry once. The Dillon is going to run right out of the box. They are easy to setup and maintain. The Lee's are notoriously finicky. Priming off press defeats the purpose of a progressive.
And who said reloading 9mm was hard? Loading w/ cast bullets requires more attention. But reloading jacketed is as easy as it gets. It's a pistol round so there are no arduous brass prep steps.
Start w/ an LCT since it's economical and very versatile. Look at Dillon's line of progressives and determine which one suits your needs if you want to ramp up production.
