The Dillon Beam scale, RCBS 505, Hornady scale (all the same scale basically) or an RCBS 1010. All good scales. Simple to use, dependable, no fickle electronics, perfect for checking a powder measure. If it's not an item you'll more than for checking a powder measure (Likely to be your situation.), then a beam scale will do a good job with no troubles. Be sure and get a check weight calibration kit. RCBS sells a good one.
I have a Redding and wished I'd bought the RCBS 1010. Over the past few years, I've had the opportunity to try out most of the scales on the market, through nothing more than sheer being in the right place at the right time. My plan is to sell my Redding and get the RCBS 1010 due ot the really nice fine adjustment.
