Pickering xsv/4000 replacement stylus insights

Dear Raul,

I had no idea it was of value. Since the stylus is replaceable I would think that only the cantilever would get old and the rest of the cartridge would be reasonably ageless. Would you agree? If this is an accurate assumption I will purchase the replacement.
Thank you so much for your time and consideration.
P.S. I have been enjoying the music.

Sincerely,

Drew

Gentlemen, Gentlemen, Gentlemen....

Now my concern is that the choice of original replacement stylus which is Stereohedron or a non original which is Shibata. The original replacement is $190 and the Shibata is $90. How good can the non-original replacements be? Any insights into original vs. non original and Stereohedron vs. Shibata will be greatly appreciated.
Thank you.

Sincerely,

Drew

Dear Raul,

I know that I could be trowing money away by being cheap. I won't buy the cheap imitation.
Thank you for your time and insights.
