You may want to get two different presses, as the large magnum rifle cartridges are at one extreme (long, lots of friction, lots powder, relatively few cartridges needed per batch) and the eventual handgun cartridges are the other (high volume, no case prep, hardly any friction, short throw, low charge weights).
Any single stage press large enough for the cartridge should be fine. If you are looking for top quality and price is not an issue than all Redding gear would be excellent investment. All will work but I think Redding has many more options for fine tuning precision rifle cartridge loading. You will be neck sizing only probably, so get neck sizing dies not FL. I actually like the Lyman neck sizing dies because they use a carbide sizing button so no need for inside neck lube. But you can buy the Lyman stem with adaptor for RCBS and Redding dies, too. [BTW, I use mostly Lee equipment for my purposes but have some dies and tools from almost every manufacturer, so I am not a Redding fanboy by any means.]
The issue with powder measures is the diameter of the cavity the powder fills up. The more narrow it is the better for small charges like 3 gr Bullseye, but then not so good for 80 gr of magnum rifle stick powders. So you want a measure designed for large rifle reloading (I don't know which one, but it is important to match the measure to your needs). When you get around to loading .223 and pistols you likely will want a different measure along with a different press.
Basically, I recommend optimizing your set up for magnum rifle reloading and just figure you will need different press and measure to optimize for .223 and handgun reloading.
