When it comes to weighing powder charges to check what my powder measure is throwing, I do not trust a digital scale that much. I use one to weight my cast lead bullets to determine what weight my mold is throwing with a paticular lead alloy.
One problem about a digital scale is that if you have florescent lighting near your digital scale, it can at times throw the scale off on it measurement. I prefer my RCBS beam scale to check powder charges.
For a beginning reloader, I do recommend the RCBS kit as being a great one to start with. You will still have it 30 years from now and pass it on to your kid as they do not wear out. My RCBS kit is over 35 years old and still going strong and still reloading very accurate rifle ammo.
I use a Dillon 550 progressive for my pistol reloading.
