I liked the RCBS hand priming tool---whatever they're calling it these days. The Lee tool worked fine, but it was subject to wear and sometimes breakage and the strain on the thumb was not too much fun when priming large numbers of cases. The RCBS hand priming tool was better in every respect. I went to the RCBS bench mounted tool, though, because it's easier on the hands when they become a bit arthritic. I find that the bench mounted tool offers much better feel than I expected.
