Unless you’ve bent the exiting cantilever it’s not now you need to worry about the cost, take good care of your cartridge and it will have gone up when the time comes anyway.
I have the other current Ortofon with a Replicant 100 stylus on an aluminium cantilever and had to get that rebuilt because I’d messed up setting the bias and after a year of daily use the cantilever wasn’t in line any more, not bent but misaligned.enough to produce intrusive sibilance where it hadn’t existed before. Take care with your bias setting.
