Old Blue Point Special- worth replacing stylus?

I have a 20yr old Blue Point Special on a Rega Planar 3. Is it worth replacing the stylus or should I get a new cartridge for approx the same cost?
Call Music Direct and ask them about Sumiko's trade-in allowance for the Blue Point line. I just got $100 off a Blue Point Evo for my old BPS-II.
Couldn't hurt to ask...
Depends how fond you are of the BPS. As former owner I came to find it so wiry and bright that I would have given mine away. But if it sounds good to you in your system, most replacement carts might well sound dull and overly laid back. Good luck.
