Evidently, VK5OQ has several.  Sorry - don't have an email address for him, but he's good on QRZ.COM as far as I know.
 
As usual, my first stop for surplus rocks is "The Great XTAL Swap Page":

Bookmark it!  Better yet, sit down and make a list of YOUR surplus rocks, and forward it to me for inclusion.
