You would be money ahead with a Diamond. And I think get a better job. I have never heard of a Diamond wearing out.

I do not make the Buying Decisions, or have the power to spend the Association Money. The Diamond was considered, they had the brochure.
Think the replacement Ball Stars were replaced on a warranty situation. But during Transit time we were without Ball Polisher.
I also know the Ball Stars Units go thru a lot of the Circular Pads .
