I must say i've been using my SP-10 mkII and it wasn't serviced at all, everything was just fine. It wasn't re-capped, calibrated by anyone except for the Matsushita factory. I've never noticed any issue in 5 years of using it and now my friend using it.
If you have extra cash you can re-cap and calibrate, but if your SP-10 mkII does not have any problem in operation you can just use it.
