Hi Andy!

I believe bob is right.
They made 1000 sets. all chips had serial #'s
I think they released on chip a month.
And the only way to get a same serial # set you had to win it.
Someone offered them a while back at $450
I always wanted one and found a source that had 5 which sells them at $250.
So i offer it to some of my customers at $300
