If you find used die sets cheap, you can add an individual carbide sizing-die. Might save some bucks.
Some of my rifle die-sets are over 50 years old and they work just as well now as "way back when". Absent abuse from hammers and rust, presses never wear out.
For the cartridges you're loading, a good used "C" press will work just fine. If you go on to full-length cases of the '06 variety and full-length resize, the "O" press will avoid what little "warp" might be found in a "C" type...I've loaded a lot of sub-MOA '06 on a C-type.
