I have a PACT electronic scale that I bought new from PACT in Texas years ago. Sent it back once when it was misbehaving. Works fine now. The very nice people at DILLON precision have their BBC scale that is okay too. Electronic is the way to go. Way more precise. The balance beam units only have a sticker applied to the beam arm. I once dropped a unit measure on my electronic scale and then measured it on a balance beam. The balance beam was out 1/10 of a grain....
