Just curious- what's your reasoning for this belief? Did you have a bad experience with an inexpensive digital scale?
Indeed, I have.
I've done quite a bit of testing, particularly with trickled charges.
Electronic scales that were not designed for reloading do not respond well to trickled charges, or light charges. Even some scales sold as 'reloading scales' were not actually designed for the task.
One properly-calibrated Cabela's "reloading scale" was actually found to repeatedly display as much as 17 grains less
than the actual charge in the powder pan, with powder charges as light as 25 grains.
I've been reading a lot of bad things about recent-production Hornady GS 1500s, too. So, I would steer clear of that one for the time being, as well.
