Nova609, I went to an auto powder dispenser (Lyman) last year at Christmas and it is a good bit faster. All the work that you would do with your hands and a balance beam scale is no longer necessary. You can do other stuff while your dispenser is throwing and trickling your powder. I started with an RCBS 1010, went to a PACT digital scale, and then on to the Lyman. I still use the PACT for weight checks, but the RCBS 1010 hasn't seen the light of day for over a year.
It's not twice as fast, but it is faster to some degree. I do not anticipate going back to the RCBS 1010.
