+1 on the Dillon Super Swager - I love mine. One word of caution, though - you only want to swage the primer pocket just enough that the new primers will seat. You don't need to remove all visible traces of the crimp.
If you swage the pockets too much, you'll end up with loose primer pockets, or you may have trouble getting the cases into and out of your shell holder. But it's not as finicky as it sounds; once you've adjusted the swaging pin to the correct depth, you can swage cases as fast as you can swap them out and pull the lever.
