Stylus replacement for Shure V-15 v MR

Hi All, I have two Shure V-15vMR cartridges that, like many, need new stylus. Question is: send in to Soundsmith for a re-tip and if so where is the "sweet spot" value wise of their three levels of service? Know each level provides a better end product but enough to justify the expense? Any opinions?

Also, any opinions on the Saunders replacement stylus that is now being marketed at very reasonable price ($79) Is this close enough in sound given the substantial savings?

Lastly, is the V-15 reputation more myth than material. I know it is a very good cartridge, but is it better to just invest the same amount of money into another make/model?

Any opinions greatly appreciated before I decide on a path to take in bringing these back to life.
