Electric drill sharpeners.

Does anyone have any recommendations?

Don't want super expensive, but then don't want dirt cheap because they probably won't be any good.

Looking at this one on Amazon. Seems to do what I want it to.

I have the early (green) version of this - and it's very good! Mine came from Spaldings of Lincs and was around £80, many years ago.
Hardly worth the effort for 3mm stuff as you can get 10 packs from Screwfix but for others it's really effective.
Buy a spare green wheel for it if you can.
