Supex SDX-1100r Phono Cartridge

Anybody own or know anything about this cartridge?  I see one for sale on Ebay that would probably need a retip soon.

I owned a Supex sd-900 cartridge many years ago, and I really liked it.

Does anyone know if I can still get a retip done on this cartridge?  If so, who can do it?

Any info would be appreciated.

Thanks.
