I'll sell you mine for $100 since it's no longer made and a collector's item....(I'm kidding).

In all reality, that video shows that the tool scratches the sight. It's not like you'll be cranking away at the thing as you'll adjust in small amounts (clicks) to zero. Good luck finding one. I'm not sure if anyone can be of service. Might as well post in the classifieds and see if anyone has one for sale.
