If you use a Technics 1200 stock arm, it would not be able to balance the heavy 30+ gram mass of SPU-GT on the end of it nor would it be a good match even if use a heavy custom counter weight IMO. If you do upgrade your vinyl setup and plans to use the SPU, Schick, Ortofon 309 and Fidelity Research FR-64S are all good arms for SPU.
As for rebuild, Expert Stylus & Co in UK can rebuild SPU but there is a long wait.
