I used to be a supporter of beam scales. But I think electronics are getting better all the time (and cheaper). I ended up converting to the Pact Pro and never looked back. I still have my RCBS 5-0-5. Solid scale.
As far as dispensers, electronic dispensers will do a lot of the hassle work for you. The problem with volumetric measures is that it's impossible for a measure to throw the exact same powder charge every time. Even high end Harrell measures. The electronic combo will measure it one and verify it every time. It's as if you hand scooped and measured each charge, except the electronics do it for you.
