Most of the time, I use the priming tool built into my Dillon 550B press. For non-progressive jobs, I have an RCBS bench tool with a tube feed. It is very fast, easy to use and offers excellent feel. As a backup, I have a couple of RCBS hand priming tools, which also have very good feel, but are tiring to use.
I have never used nor installed a priming tool on a single station press. The ergonomics aren't very good compared to other methods.
