I purchased a digital scale from Dillon Precision over 15 years ago. It plugs into a receptacle near my loading bench. I often check the accuracy of the scale with some Lyman weights. It has been a great scale! Mine is accurate to +/- .1 grain.
Because it's "electronic" and my loading is done in a "mostly unheated" shed in NH, I remove it from the shed when done and keep it in the heated basement. I have a propane heater and heat up the shed for 1/2 hour before going out there to reload!
I got the RCBS ChargeMaseter Combo a few years a go and very happy with it. If I ever go UBER-precise I might look for a slightly more accurate precise on the measurement maybe going down a digit. It has made some very accurate rounds and I am NOT complaining. Of course you can always improve but don't take this as it is anything not worthy as it surely is. YMMV
I also bought a Chargemaster (on sale) a year ago, but have yet to use it. My purchase was more for rifle reloading than pistol. When I retire (soon), I'll be working up loads for my rifles and using my LabRadar to determine velocity vs. accuracy. Can't wait! Less than 1 year away!
I'm not a reloader (yet), but ran across a video the other day that may be of interest...
This is from the youtube channel "Johnny's Reloading Bench". The video, which was released 2 months ago, compares 16 digital scales that range in price from mid-teens to close to $100, if I remember correctly.
For me, being the nerd I am, I did a statistical analysis of the charge weight from the Dillon scale. Once I determined that the standard deviation was +/- .05 grain, I was confident in using it! A .1 grain difference will not cause any over-pressure rounds if I reload close to the max!
As with so many things, it depends on what level of accuracy/precision you need. For some time, I used a Frankfort Arsenal (IIRC) scale that was rated at +/- 0.1gr. That was fine for mid-range pistol rounds and bulk rifle ammo (55gr 223 in my case). But when I started trying to shoot the tiniest groups I could, the scale became a limiting factor in my reloading. I switched over to a GemPro 250, which is rated to +/- 0.02gr, and saw my velocities, SD, and groups all shrink.
