Recommendations for replacement alternator noise filter?

[j3pup]

Does anyone have any recommendations on a replacement alternator noise filter? The one on my plane translates to part # S1915-1 which is $95.20. Any cheaper filters out there?

Some info. Hope it helps. Unfortunately, nothing is cheap for our airplanes.
