98 RL 210k miles, about to replace timing belt, accessory belts, tensioners and water pump.

Since the timing belt must be removed to replace the CKP sensor, should I just replace it proactively now? It's not an inexpensive part at almost $100 from RockAuto.

Any feedback on the reliability of these sensors?

I also have a 99 Saab 9-5 wagon and those CKP sensors are notorious for failing. I've replaced mine twice in 260k miles.

Thanks!
