I have the Sinclair tool, and I guess it depends on your personal needs, but you can do say 100 brass in an evening, or one TV show (been a while), After that, I'm good to go for a while. I only ever used it on my .222 brass, and it's not as though we have the prairie dog shooting some have, but since it's a one time/case operation, I can't see adjustment being a big problem, though some seem to be finding it so with their particular needs. Now if it was like reloading dies and I had to reset every time I loaded...
