97 Tahoe Abs Braking Problems

Hello from Germany, it look like i am in good Company with my Braking Problem. Because many of the Tahoe Owner have it. Acording to the suggetions in this Forum, i take the 2 Front Abs Wheel Sensors out and clean them. But the Problem is still there, so my last hope is to replace the right Sensor because the Cover of the Harness is broken and i can see the 2 cables in the inside. Now my question is where i can get a Abs Wheel Sensor for a fair Price. Because here in Germany the Chevy Dealer wont 135$ for this small Part. So i hope you Guys can help me.

Greetings from Germany, and sorry for my poor English
