Where to find Crankshaft Positioning Sensor?

Any of you all know where to find this sensor online? Yamaha wants $120 for the part and I'm sure I can find it cheaper somewhere else other than the local Yamaha dealer. My bike's been down for a month or two and I need to get it running again so I can put it up for sale. If any of you all have any info, please post. Also, anyone that's messed with replacing theirs,; If you have some tips let me know. I plan on doing this install myself. Thanks, Roque

did you try ronayers.com or mrcycles. there stuff is like 20% off what dealer is. course you have to pay shipping. or ebay.

I searched on there, but didnt find the part. I dont know if there's another part # for it.
