Most of the commercial magnetic dampened beam balance scales are quality units, that is Lyman, RCBS, Redding, Ohaus, Hornady etc.
The Lee, looks pretty cheap to me, but never having used one, I can't comment on how it works, and that's the important part, and we as shooters should no better than to pick on something by appearance alone. That's a politicians game.
Electronic scales, are I understand, faster, however, for a guy that reloads rifle only, unless you do a lot of shooting, and want to weight every charge, a beam balance can work fine, and they are not as slow as some would have you believe..
Me, I use an RCBS 505.
