This guy has been around for a while, and he's always overpriced the stuff he has for sale, but I was actually pretty impressed he had one of these for sale. With a certificate of authenticity, to boot.

Now all I have to do is put a second morgage on the house and sell the soul of my firstborn to the devil, just so I can afford it. I can't believe they're actually worth this much, but then, I've never seen one for sale before. So, who knows?
