I have a music hall mmf-5. In a unfortunate series of events I broke off the decoupled stem for the counterweight on the Project tone arm. I talked to the manufacturer who told me that I need to replace the tonearm. I plan on purchasing a new table, but want to keep this one for a second system. Does anybody have any suggestions for a tonearm that would be below $300 and would be able to be incorporated without to much retooling of my existing table?

Below is the broken tonearm.

Thanks
