Have you tried Dave's Books. Here is the linK: http://www.daveargabright.com/

If he is out, which he probably is, I have an unsigned copy. I believe I paid $30 plus shipping. Is this for a gift ?
If Dave is out, e-mail me. I would be willing to let it go for a good cause for what I paid for it plus shipping charge. I have all of Dave's book, except his new one, all autographed by Dave and who the story is about except Jack Hewitt.
