Paradigm ADP 590's

I am in dire need of a used ADP 590. One of the tweeter/mid assembly went bad, the factory wants $484.00 for that one piece even though I only paid $900 for the set new. Frustrating to say the least. Shops tend to only want to do warranty work so they get a new part and exchange the defective one. There is one on ebay for $300. Imaging that, an 11 year old speaker and only one at that.. Any suggestions outside of biting the bullet?  
I have a pair (version 5) that I can sell you for $500 plus shipping.
Let me know if you are interested.  They are in pristine condition and lightly used.
