Free 3d Greeble/Detail Libraries?

Zepic

I was wondering if you guys had any links to free greeble/detail libraries.
Something similar to this thread over at ZBrush Central.

This is a year late, but a decent place for greebles/nurnies:

http://www.badking.com.au/site/shop/industrial-custom-brushes/nurnies-brush-set-01/

http://www.badking.com.au/site/product-category/custom-brushes/industrial-custom-brushes/

Honestly, the whole BadKing overall is a useful resource.
