A few words about this particular seller;

He WILL NOT SHIP, for one thing. 
He's had this for sale every summer for the past few years. 

I have read the accounts of several folks who have tried to buy it, and resulted only in frustration. 
I have tried to buy it myself, about 2 years ago. 
I was willing to go up there to get it. Not easy to deal with. 

I was tempted to make the personal trip up there at one point, but figured that even with cash in hand I should factor in a 50% chance that he would not sell once I'm there/not meet with me/etc etc....
There's a thread on samba from a year or 2 back.
