Go with the Lee Anniversary Reloading Kit. It has the cast aluminum "O" press as well as almost everything you'll need - except dies and cartridge components - to start reloading. Depending on how new a kit you get, it will have a copy of
Modern Reloading or
Modern Reloading II by Richard Lee. You can get this kit for about $100 if you shop around.
By the way, you'll need at least 3 reloading manuals to start with -
Modern Reloading (I or II) and
Lyman 48th Edition Reloading Handbook are two I strongly recommend.
