Your range of units costs is about right for an electronic scale...
Googled this morning:
RCBS Rangemaster 750 @ $102
Lyman 1000 XP @ $99
Hornady 1500 Bench Scale $77
No endorsement of any of these as I have a Pact.
The biggest electronic scale benefit is the immediate readout and the savings of time in the reloading process. GB and others have penned it right...
a scale is not all about how perfectly accurate it is, but how consistently it throws the charge or reads the same weight.
Repeatability is the key.
Consider the rifle reloader that weighs every brass case wherein weight is a means to verify internal case volume. Just one more little tiny step on the road to repeatability in the Quest for Accuracy. This effort can and is routinely performed on many balance beam scales. I have done it for thousands upon thousands of cases on an RCBS 5 0 5 balance beam scale over years of reloading.
Following my purchase of the Pact electronic scale, I found case weight measurements to be practically instantaneous, reproducible, a significant time saver, and I won't be going back to the 5 0 5 for this task.
I have weighed the same case and 2 independent check weight sets on the balance beam and the electronic scale finding 0.10 grain of difference. Each instrument is advertised to be within +/- 0.10 grains of true. Did that difference bother me? At first, YES. Yes it did. I was initially concerned. Then I relaxed, reduced my pucker factor, and reread what GB and others had penned...
consistency is the key.
Now, instead of reporting that my favorite 5 0 5 charge weight for "X" caliber is "Y" grains of Belch-fire powder, I report the charge weight measured by the Pact as "Z" grains. I still achieve the same repeatable accuracy through my rifle, which is greater than I, the Weakest Link, can hold, but I achieve repeatably weighed rounds in a
significantly shorter period of time at the bench allowing me more time at the range or in the field.
This contributes one of the factors to the Internet being a poor place for "trusted" information in starting loads as your face is within 4-inches of a 35,000 to 60,000 psi "bomb". Consider that and be Cautious.
