I have always used an old balance for weighing out my coffee. The cheap digital scales all seem to have a problem with re-adjusting the tare when you add just a few beans.

I have found this to be a problem with electronic scales of all prices that use strain gauge technology. Drift is a big problem with strain gauges, which by itself can cause the tare to change. So scales based on strain gauges use drift correction, and small changes in weight are detected as drift, which also causes the tare to change if the small change in weight is due to weight being slowly added.
