No clue. But, I think Tanner sold one on the classified a while back.
I think I sold it for $1300.
STS-65s are badass.
I ended up with this one from Tanner and it is great-side by side with my STS-65 HD there is no noticeable difference to the eye. If I was to do it all over I'd probably get the non HD since I don't use it with a camera. Tanner is correct, the STS-65's are bad ass.
