Personally lean toward the mechanical side that I can check, tune up if ever needed, zero out, and don't need power or batteries. My 1960's Lyman balance responds to a single flake or kernel of powder.
Is yours an M5? That's what I have made by Ohaus for Lyman. I think Ohaus made the 1010 for RCBS as the older versions look almost identical to the Lyman M5.
