Old F--t here, unless your going with a complete powder dispensing system Lyman, RCBS or Pact I'd stay with a good balance beam scale. One of my favorites is an old Redding oil dampenned rig, most of my scales are at least 30yrs old, never had to change a battery yet and if something is amiss you can see it right away and they don't need to be callibrated each time you use them. I keep a scale at each press and one in reserve the Redding, Lyman M-5, Lyman D-5 and RCBS 5-10 only the RCBS has had to go in for repairs, corosion on one of the knives.
