I have a Hornady single stage, a Lyman turret press, and recently got a Hornady progressive. Only been reloading for 3-1/2 years and not high volumes, so YMMV.
I only use the single stage for rifle hand loads. There are only two dies and you need to do case prep in between those two steps. Plus I prefer hand priming so I can check every primer's seating depth by touch. That's especially important for service rifles with floating firing pins. Finally, .308 Win requires a lot of work to resize and I don't want any deflection when doing that step. Don't want any deflection when seating rifle bullets either.
$325 won't get you close to a Hornady progressive. Don't forget that you'll need dies, bushings, and shellplates.
If your budget is set and you're only loading for pistols, a turret press might be a good alternative. No, it won't be as fast as a progressive, but it can be a lot faster than a single stage. Size & bell, then hand prime, load in trays, then seat & crimp back on the press. Probably can find a Redding T-7 or Lyman T-Mag II used for a good deal too.
I like the Hornady AP for longer runs of known-good hand loads. However, if I could only have one press for pistol rounds, it probably would be the turret. Especially if I were on a tight budget. I'd rather spend my $$ on quality dies, brass, powder and bullets.
