I had a 505 and eliminator as of last week. Both made by Ohaus, they looked identical, only difference that I could tell was that the RCBS has a ounce to grain conversion table on the side and of course the color difference.
I had an old 5-10 scale that was probably older than I am and it wasn't quite coming to rest at the exact same spot every time with a check weight, I shipped it to RCBS for repairs and I guess they were unable to repair it. They no longer make the 5-10 scale and I think I was grinning ear to ear for a week when I opened the box with the returned scale to find a brand new model 1010 in it's place. RCBS knows how to build customer loyalty.
With all that said, if I were looking at a NEW 505 or Eliminator I'd have to save my money and buy Dillon, yet another company that knows how to build customer loyalty.
