is what I found. I started out w/ a 550B, then sold it and went to a 650. Did not care for the latter press due to what you described, so I sold it to a friend (who still has it), and bought my 550B back. It is now 30-years old and still going strong. I use it for everything done in large quantity, even though I have six other presses on my bench. I now reload thousands of .45ACP each year w/ it, and will be doing at least 10k rounds on it this year.
