Is that 300 to 500 budget for everything or or just for the press itself?
In addition to the press at minimum you will need a die set for each caliber, a scale to check the powder charge, calipers for bullet seating depth settings, primers,cases, powder, bullets, a tumbler to clean the cases etc etc
I bought a progressive when the wife was going through pistol ammo like grease through a goose. Even though I had been using a single stage and a turret for years I found the progressive easier to make a mistake on and get a double charge or a squib. Mine sits under the bench most of the time these days only coming out for binge loading pistol fodder by the hundreds.
You might want to consider a turret, they are a good compromise between single stage and progressive
