a/c vent broken, need part
 

In my '02 S4, the A/C vent left of the steering wheel is broken, the swivel only moves the middle blade, the other 4 blades are loose. Internally, the little connecting beam has let loose. Local Audi dealer says I need to buy a whole new vent, $84.

I'm pretty new to the Audi scene, is there any way to get cheap parts in the US, or is there maybe some kind of second-hand / salvage part dealer that can get me just the swivelling part for less than $84?
