I will repeat myself. I buy such items from Rob at Needswings. I paid around $46 for mine from him - Iv'e never had a bad part from Rob.
This is the third one I've ordered from Rob (two went on the Graphite, one on the SE). EVERY time I change the stabilizer, I am surprised at how different the car is - probably cause I let it go WAY too long - and my love for curves means that the part is cycled tens of thousands of times in a year!
