For starters, get out your crystal ball and anticipate future needs in terms volume and process. I suggest a progressive that will grow old with you. A turret (one pull, one task; four pulls for one complete round if separating seat and crimp) may have you longing for a progressive before long. A simple Dillon 550C, which has four stations, performs seven tasks with one pull (and slight push for priming), yielding one complete round with every pull. Is body wear and tear a concern...over how many years?
Consider the features available. Auto index or manual? Will a four-station do or might you want to trim rifle cases and/or install a powder-check, necessitating a 5-station, or more? Changing calibers can be very time-consuming (and expensive) on some progressives. Perhaps add a case/bullet feeder someday? How important is the warranty? Tech support? Handgun only (see Dillon Square Deal B) or rifle also? Ancillary items, such as a mount, light, bins, dedicated toolheads/measures (so as not to fuss with dies), etc. will run-up the tab.
Take some time to read-up and ponder the options while gazing into the ball. Share your budget, present/future needs (cartridges, quantity, changeover frequency, etc.) and applicable info will be forthcoming. If you need to slowly acquire all the items over the course of months, do it. A Dillon BL 550 is something you can grow into. Buy right and cry once. I get the budget aspect and don't mind spending time at the bench but no more than necessary...rather be playing with kids in the sun.
