A Prometheus is by far the most accurate that I've used, but what bunch of pieces. I use a Harrels pistol measure for very small loads, a Jerry Hensler modified Bruno measure for 25-35 grains of powder, and a MCRW for the rest. The MRCW is a Lyman 55 clone with a Teflon coated body and the rest is a SS Culver conversion.
