i was watching this Ebay auction too!
I saw it go up to 20K and then..must been a retraction as i saw it fall back to 16K with a few days left. Figured it go for more$- near 40-50K, but 30K is not too shabby-shique.

I saw this was the 4th type mount, which is very hard to find, as it seems only 3-4 on most of them at best, from what i read on Heritage's site.
Awesome WIN!!!
