I actually have AT-ML180 OCC with broken stylus, i also have AT-ML150 OCC with broken stylus from the AT-ML170.
Everything still can be competelety re-cantilevered or fixed by SoundSmith or Expert Stylus companies. The total cost of this job is not so expensive as nandric said, if the cantilever is Ruby by SS.
I’m pretty sure it can be a very good cartridges and there is a chance to find genuine replacement from the lower models to use or to transplant. At least MM styli are interchangeable. Fixing a broken stylus does not mean that you can not use the original stylus as a bonus.
