While the scale you link to is probably a very good beam balance scale, you will find in short order that a beam balance scale is not ideal for the task. In the "olden days", they were all we had available. However, measuring an unknown value is an extremely tedious process with beam balance scales. You have to zero the unit, guess at your weight and move the weights on the beam, make a measurement, move the weights a bit, make another measurement, etc., etc.
With a digital scale, once it's set up and zeroed (something that must be done with any scale, though with a digital scale it typically only requires pushing a button) than all you need to do is put the unknown weight in the pan and, after a little time for stabilization, read the value.
As I mentioned before, you'll want a firm vibration-free surface for any scale (but especially for a digital scale) to get the best results with them. I have my scale on the same bench as my press, but I don't make weight measurements and use the press in between the measurements. I do all my powder weighing in a work flow session that doesn't require using the press.
The bottom line is that I think you'd be a lot more satisfied with a modern digital scale. I suspect that many of the negative reviews that you've seen may result from the person doing the review not really knowing much about scales and how to properly use them.
I used to occasionally do maintenance work (repair, cleaning, calibration, etc.) on precision laboratory scales and balances during my career in industrial process control systems (I'm retired after 39 years in the business), so I have a good idea what makes them work and what's needed (like the solid vibration-free surface) to make them perform up to spec.
