Given the calibers listed and presumed usage, you'll likely find yourself in hell if you decide to go with a single stage press. Single stages are great if you are doing low volume for extreme accuracy or some of the more off the wall calibers. However, there really isn't that much potential cost savings in either .223 or 9mm for general purpose "plinking" loads, or generally for caliber where military surplus is available. Not to say there isn't any savings, but the time investment required for single stage loading isn't worth it for this, IMHO. While I don't find reloading tedious by any means, spending an hour loading what could take a few minutes to shoot and only saving one or two cents a round is pushing it for me. And given that you say the .223 is for a "black rifle", I'm guessing you're needs will tend towards the plinking end of the spectrum, vs. extreme accuracy, and so you'll want to do a decently large volume.
In your case, I'd guess you'll eventually want a progressive press. Dillon 550b is probably considered the standard by which all other presses are measured. When you can crank out around 400 rounds an hour, loading such calibers like .223 and 9mm, which have slim savings per round, start to make a bit more sense.
Arguments for or against starting out with a single stage - I did this and still on occassion use the single stage for oddball stuff. However, if you only plan on doing .223 and 9mm, I'd guess you'll never touch the single stage once you go progressive. In that sense, you'd be "losing" the money spent on the single stage.
