Balance beam vs digital scale ... any impact from humidity / temperature?

[Lead hammer]

Picked up a cheap back-up camera and a display for it from Amazon for about $40.00 total; add a 12v battery, some wires and a bit of time to mount it so it's totally stationary and consistent from session to session, and (I think...) the human element is pretty much removed from the process (aside from my fumble-fingers bumping the trickler at the wrong time...).

Mine sits on top of a box of Hornady 180 grain 357 mag bullets. Just the right height.

Had the little Hornady Calculator size scale, never trusted it, always had to use the weight to be sure then I got a Dillon beam scale when I started reloading bigger calibers, took the batteries out of the hornady and stored it away no regrets.

I use a beam scale because I want the precise repeatability of it. My main concern is that all of my ammo is made to the same specs, and a cheap beam scale ensures it is, whereas with an electronic scale that may or may not drift, I can't be certain without frequently checking it with a calibrated weight. Would love a high end electronic w/ auto trickler, but can't afford one.
