Replacing just the stylus has never been particularly economical when compared with the price of a whole cartridge, so don't be too emotionally attached to the old one. If you want a good, reasonable, durable cartridge, look at the Audio Technica line- fair prices, good sound and they'll work with your turntable's tone arm. I would pass on the P-mount models- just get the kind that has two screw holes in the top of the mount, like the AT-155LC (which is a really good cartridge).
