You never know a) what will motivate a collector and b) when just  the 
right collector for a given item will show up. Every day I thank my  lucky stars 
they didn't, for whatever reason, show up for my Mark-8  boards.

With the "No shipping cash on pickup" proviso the seller  provides, I 
feel fairly certain no one's biting. But I've been surprised  before...
