Linn Sondek LP12 - Cartridge recommendation

Kind of new at this hobby and looking for guidance. I purchased a Linn Sondek LP12 (Valhalla pwr supply) with an SME Series 3 tonearm. The cartridge is an AKG P100 but the tip is broken (this was reflected in the turntable purchase price). Not sure which way to go..should I have the cartridge repaired (was quoted $325 for repair) or should I simply replace it with another cartridge ? What cartridge model would work best for this turntable ?

Thanks !
