I have a chance to buy a RCBS beam scale made by OHAUS for RCBS but I would like to know if they are any good, what is your opinion? I have looked at it, it is used but in great shape. There are no model numbers on it, it only says made for RCBS by OHAUS. I know it is old but most of them work fine, I will take my RCBS weights and make sure it measures what it should. Let me know, he only wants less that $40 bucks for it, I think it would be a bargain???
