Thanks for the lively input everyone and please can we all keep it civil, we don't need to fall out with each other over a tonearm question. Opinions will and do vary but each to their own in the end and for me it's probably worth getting the SME 1V serviced and rewired then just enjoy it for many years on the Oracle Delphi turntable.
It's got nothing to do with vanity etc, simply that I can and will go ahead with my investment for the future and end up with a virtually new SME 1V with latest spec bearing same as V and better internal wiring and then simply enjoy.
Or sell it and put the money towards buying a V?
Also be careful about what the 'better' internal wiring. The earlier 309's and IVs used OCC copper wiring, the later and V's used silver plated OCC. I prefer copper, so its not so much about whats better, more what you prefer.
My V cost £1900 and is in absolute mint condition.
