$50 from The Exterminator on Amazon.com...still a more or less reasonable price for this long oop 2-discer I guess...maybe it will pop up again at the CR store?
I doubt there's many copies left in stock though.
The CR dvd is probably the best release of Stunt Rock,also CR created the new transfer (also used by the Aussie disc) it seems.
