l just use a cheap honady set of scales but do a calibration each time and also check against my old balance beam.
my main issue is that they still have a bit of a lag time settling and will roll up another 1-2/10 gr after a few seconds.
had an interesting experience recently with the battery's getting flat.
Calibrated OK but when i weighed my powder pan it was about 10gr heavier than memory thought it should be. weighted out 3 lots into cases and the level in the case looked low. So pored a load onto the balance beam and it was 3gr light.
got new batterys and all was good again.
