Consider the RL550B, its a great press, I have loaded over 50,000+- rounds in 12 + years on mine, and the auto index is not needed at all. Even with an auto index you still have to pay attention to what you are doing. Right now I have a 550, and a Hornady LNL on my bench, I have owned the Hornady for about 6 years, 12,000+- rounds of .45 acp loaded on it. Its also a great press but requires a bit more tinkering than the 550 to keep it running. Due to ergonomic advantages I can still load faster on my 550 manually indexing than I can on the LNL with auto index. I have broken a seating die on the Hornady, and an indexing pawl, and a few case retainer springs, the primer shuttle is worn out on it as well. The Dillon, I have only replaced a plastic primer feed tip. On the 550 I index the shellplate with my left thumb as I set the bullet with the left hand, the right hand picks up a case and puts it in the press and then pulls the handle, the layout of the press facilitates this happening very fast with a little practice (ergonomics).
