There are some stand alone ones.
Really whether AC or battery, doesn't matter just as long as it's not the cheapy- $10 one from Chinkland.
Trust me, at our age we don't need the aggravation of reading down to those dinky, blurry manual scale lines!

I went with the combo so the dispenser and scales could talk to each other.  then throw, wait, visual check, and dump into case.  Rinse repeat, lol.

Fluorescent light can throw off some electronic scales as well. Even though I haven't had much problems with them, I'm in the process of changing my fluorescent lamps to LED lamps.

Another thing you can do to reduce interference is to wrap your scale's power cord around a ferrite device (sometimes called a choke) to lessen any interference from your 110V 60Hz power source or any other electronics that might cause interference. Wrap the power cord once around the choke & snap it closed. Another ferrite device is a torroidal core ... looks like a donut. With it you can wrap the cable through it several times.

AND using a consistent procedure, each time, every time...

After, what, 20 years of using an rcbs, I have never seen any electronic drift or interference, and this from an ex-electronics tech (Nav).  That is, unless your lighting gives off excessive buzz or crackling noises (mine doesn't), or live in downtown Chicago where the ele is pretty nasty with voltage spikes and such...  I'm plugged in to 120 vac, live in a small town, but hey, if the battery style works for you then go for it.
I'm a pretty heavy reloader these days in retirement.  I do do the soda straw mod and have tweaked the A, B, and C constants, so it runs very smoothly.  Anything over by 0.1, I toss back and re-weigh.

2. Buy a check weight or make one and periodically check when loading. It doesn't need to be any precise weight (a small stainless washer bent in half at 90*), just something you know the weight of that's close to your charge weight, especially when using a digital scale.

Even cheaper mechanical beam scales are surprisingly accurate, repeatable and reliable. I use a web cam hooked up to a laptop to read the scale on mine. I also brought the pointer to a sharper point and colored it. Way easier on my old eyes.

I also recently bought a Ohaus SPX123 used on Ebay for $130. If it was ever used it wasn't much. I plan to use it mostly for loading my 6x47 ammo for long range. You can find deals there if you keep your eyes peeled.

You got me to thinking , I fish and have Tungsten fishing weights from 1/32oz up to 2oz so weigh them record weight and box them for later.
