I started handloading a year ago, and with an estimated 600 rounds per month, decided to start with a progressive press.
Buy once, cry once.
If your volume dictates a progressive press, then you should consider one.
I still often use the progressive in turret "mode" if I'm loading precision charges and want to weigh every throw. If charge isn't critical (meaning- being "off" a few tenths), I will use it as a true progressive.
In any case, I don't see a single stage press as being practical for any sort of volume reloading. You can learn the "basics" just as easily on a turret or progressive.
While reloading was "fun" the first few times, I now view it as a necessary chore. And the quicker I can get a few hundred rounds done, with the necessary accuracy and safety, the better...
