I too have the latest RCBS Chargemaster. It's precise and quick, a big improvement over balance beam or the the old Rangemaster 750 I used before.I‘ve been using my first and only scale, a RCBS 505, since about 1986. It continues to serve me well.
I considered electronic scales for some time and have read about the good, bad and ugly.
Suggestions for reliable and consistent models are welcome.
