For pistol reloading, I really like the Lee Auto Disk powder measures. Once I find the hole for the powder and charge I want, they are as accurate or more accurate than the Dillon powder measure, and since there is no adjustment, there is less chance for a change in drop weight. The spring return has never given me a problem, and they cost less than the Dillon measure. I use a separate one on each of the Dillon 550 toolheads I have.
