Star Bushing Manufacturer other than Star?

Hello,

I'm looking to pick up a couple of bushings for some various powders that I'd like to experiment with. I had picked up a couple from Bruce @ Star; and all of them have proved satisfactory, save for one which came undersized- as measured with a pin gauge this afternoon. I've lost faith in service from Star as a result of some correspondence this afternoon, so I'd like to find another vendor who turns these. Anyone have any leads?

Thanks,
Chase
