I would NOT pay $110 for any used ball. One well known poster has told me that he believes asking over $35 for a ball is too much. I disagree, but there are certainly limits. I would have a very hard time justifying an asking price of over 2/3 the balls' initial value, and then it would have to be in terrific shape. Of course, if the $110 included shipping it's getting closer, but still too high, imo.
