Beam all the way. I have yet to see a digital scale be able to keep up with a trickler. You usually end up getting too much in. Beam is real time. Beam is not affected by power, or temperature.
I have tried most on the market 3 years ago, and came back to the beam. I see no advantage of digital unless you are wieghing brass or broadheads, etc. Horrible for powder. I currently own RCBS, and franklin arsonal and rarely use em.
Also most digitials available now are very open to RF noise, and electromagnetic interference from dryers, or dirty power is neighborhoods. These transducers (I have experience using in designs) are extremely sensitive in the microvolt range and power should be greatly filtered for control. You just can't design a good system for under 400 dollars.
I have heard several people say "never had trouble with mine", later found out they over loaded a shell.
