Scales
Colt1911fan--Depends on what you want to do with this scale.
If you intend to weigh a number of objects which will not weigh exactly the same (for example, sorting cases by weight) the digital scale will undoubtedly be faster.
However (there is always that darn "however"...) if you intend to weigh a number of things which are to weigh the same, such as charges of powder when carefully loading rifle ammo, it is easier to set a balance beam scale for the correct weight, throw the charge a tad light, and dribble in powder until the beam balances. You can tell how close to "on" you are getting very easily. The digital will stay at (just for example) 45.2 grains, until it suddenly switches to 45.3 grains, wheras you can see the beam getting closer and closer to "right on."
With a large-grained powder like IMR4350, I can tell with my beam scale, if I am 1, or 2, or 3 powder grains under, and drop exactly that many powder grains into the pan.
Then there are the issues of battery usage, letting the digital warm up before it settles down and gets accurate, wandering zeros, and temperature and breeze sensitivity. No experience here; I like my beam scale.
I think I would get one of those RCBS powder-charge measuring electronic units, if they weren't about 300 bucks. I have better uses for a loose 300 bucks. So initial cost is also an issue.
