... Perhaps I'm a little biased, but ALL my Dies are RCBS. Warranty is great, and I've only used it once, and that was to ask about buying a locking ring for USED set. Sent free ! ...... You can, perhaps, buy used at a fraction of the cost of new dies, but don't forget to get the little part that holds the case in place (Case Holder ). Carbide Dies are the way to go, if at all possible ! ..... MTM Plastic Boxes are very useful, and cheap, as are reloading Trays. Although to be fair, you could make your own, but really it's not worth it, and you probably couldn't run the home made ones through the Dishwasher ! Two trays at a minimum ! ..... David K
