Any recommendations on a reasonably priced digital scale? I have one of the cheap Midway brand scales that I don't trust. Trying to tare is a crap shoot on if the scale will tare or shut off. It's also not very consistent as there can be .2 to .3 "negative weight" after pouring the powder out of the tray. I'd really like to stay in the "not more than $50 category" but it seems the better scales cost more than that by a fair amount. Thanks.
