I have chatted with people that had all of them except Hollywood, and a lot of people are still using the dies from Herters, Lachmiller, Baer or Bair, and Pacific, and Bonanza. I have inherited a set of 45 acp Herters dies that appear to be identical to CH dies, except not carbide, and I have a set of Bonanza 38 super dies that seem to be awesome, except again not carbide. I added a Lee carbide die, and now all set. And I hear Hornady bought out Bonanza
