I prefer a beam balance rather than a digital scale. No batteries, and if the needle shows zero with an empty pan in position -- it's calibrated. No need to fiddle around with check weights.
The Lee balance will do the job, but it's a bit awkward compared to other beam balances (such as Dillon). Why? Because the Lee balance is made specifically for reloading. You set the scale for the charge weight you want, and the sliders are locked in place. This makes it easy to verify if the charge you just threw or dropped is correct but, if it's off, it's not as easy as a Dillon beam balance for seeing how far off it is.
I have both a Lee balance and a Dillon balance on my reloading bench. I also have two digital scales -- I haven't used either of them for over five years. I have no use for them. In retrospect, buying them was a mistake. I listened to someone who told me I had to have a digital scale.
Wrong!
