Well I pretty much got skunked this year with the excal (Just clad and junk jewelery). Can't blame it all on the machine, as I did not go frequently. Nevertheless, I can't help but think I missed something because of the poor stock head phones and crashing waves making it hard to hear. I have seen the repair you all have done, but am electronically "challenged" and fearful of attempting anything myself. Is there someone out there that is offering services to 1) replace headphones, and/or 2) add the pinpoint switch to the shaft? Much appreciated - thanks
