I just bought a digital scale off E-bay and it has worked fine so far. I received a weight for calibrating and have some lighter ones myself. I can' t see spending $200-$300 on a RCBS scale (at least thats what they charge up here). It' s good to +/-0.2 of a grain and needs no conversions. I know others are good to +/- 0.01 but I' m not that fineky....Take a look yourself. JDinAB
