Same kind of post I saw a few days ago...same answer...
Look into what is called a turret press. You can set up all your dies on a turret press. Some presses, like the Lee, have an auto-index feature...is it needed? Dunno...I load mostly for rifle and a few pistol rounds for single shots and don't really need large scale production...YET.
Since your getting into it fresh, get the books FIRST...read...as far as what the books tell you that you will need, brand-wise, take it with a grain of salt...I still have my first lee classic press...I just use it now for decapping and for pulling bullets...but its still around...my main press is a rock-chucker, though. For the rounds you plan on doing, that lee turret press will be just fine, I think. I am guessing that your 223 will be fed into an AR-type rifle, so a case trimmer might be needed eventually, as well. How you throw your powder measure will be a personal preference, I think. And priming, as well. I use a hand-primer...I actually have two...one from RCBS and one from Lee...both work good...the RCBS uses standard shell-holders (I have the old one, not the newer unit with the universal holder), the lee uses a special type of shell-holder. Both work just fine. As others have stated, there is a better feel with these units...you know the primer is going in correct.
For the 223, I would also think about a Factory Crimp die...mebbe...although there are a whole gang of things to think about...so get the books, read and you will be better able to make the right choices when you go make your investment.
