I'm confused as to why everyone feels the need to bash the guy for his thought on the value of it...
1) it IS a very rare ball to find in great condition
2) a lot of people do swear by the ball, so it does carry more value than, say, a Columbia300 Big Shot in the same condition.
3) being the supplier, he does hold the initial leverage in setting the price (before consumer demand takes its effect on said price/value).
I'm posting this, only because I've been a member of this site for a long time, and hate seeing negative feedback that could discourage someone from trying to sell on here again. The buy/sell forum has already slowed down tremendously from years past, without such great (insert sarcasm) feedback to a seller.
