I broke a piece of plastic on the fan blade assembly and now it is way out of balance. Please someone tell me there is a cheaper alternative to replacing the entire assembly for $700. Apparently they don't sell the blade assembly separate from the entire housing and electric motor unit.

I found an aftermarket I may have to go with because no way in tell am I paying $700 for a broke piece of plastic.
