NOS Ortofon VMS 30 MkII

I just bought a NOS/NIB Ortofon VMS 30 MkII (haven't received it yet). I'm wondering how these old Ortofon moving iron designs hold up against age (it's 20 years old!). I've read both positive and negative comments about NOS cartridges. It seems that some brands hold up better than others. Has anybody had NOS experiences with this model (or others from the VMS line)? Are the potential problems limited to the stylus part or is it likely that the rest of the cartridge will be affected too?
