Mission M Series center

Howdy. I'm looking to match a center channel speaker to Mission M53's (black). It's been difficult to locate a Mission M5C in black anywhere. Does anyone know where I could find this speaker? eBay has been void of them. In second, what might an alternative speaker to match the M53's be?
