Yes, there are a few, but it is several hundred dollars (at least for my Sumiko), and of course there is no guarantee that the sound will be the same. Replacing the stylus on a MM cartridge is usually not terribly expensive, and as long as you are using a genuine replacement you can expect the sound to be pretty much the same.I can't recall the name, but wasn't there a company that could re-tip a worn out MC cart so long as the cantilever was not damaged?
TBH, I hate the whole idea of nonreplaceable consumables.
