You can not have enough manuals , you will see not every bullet and or primer , powder combo is in just one manual , but you need at least one to start out with. The choice of reloader is up to your budget , as long as your budget gets all that is required. Yes they all will make ammo and some will make better ammo then others.
I'm not sure when carbide dies came out (pistol) ,but I jumped on that band wagon as soon as they came out , I've tried the carbide expander balls and have broken a couple of them and quit using them . I have a Lee 1000 and it has served me well through out the years ,but I use RCBS dies for every thing and most are over twenty years old( more like 25 ) I use a single stage Pacific 007 only because I like the angle of the main body , makes it fast to put a case in the shell holder( my first was a RCBS rock chucker and its about the same as the 007 ,but the frame is in the way to me )I also have a RCBS Green Machine in 44 mag , how many remember that progressive reloader ?
As said above ,you can see where this is leading , you will never stop acquiring equipment if you keep reloading, Buy what you can afford and have fun and be careful.
