This can be a very personal choice, alot of it is about what your loading needs and goals are, OK?
That said, I'm olde school and still prefer a good mechanical beam scale. They don't need batteries, are not subject to static variations, don't need grounding or need to "Warm up" to function properly.
I haven't seen a reliable, repeatable electronic scale capable of measuring grain fraction that cost less than 300. When guys with electronic scales are asked why their scale doesn't measure the same grain fraction of the same sample repeatably, they defend it by saying it's tolerance is within + /- .1 grain,,
well, so is a beam scale,
That's just my opinion,
buy a good beam scale and be set for life, No Batteries or power needed
