Yeah I think Jeff is MIA..
the issue of this book being so out of date is been brought up before with all sorts of ideas of how to update it.. in reality without publishing a new book and incurring the cost which many have looked into , it's hard to revise.
one Idea I had is we could just make our own "Updated" price guide kind of like an insert to use with the book if you have one.. still use the images and condition ratings that are in the book but just a reference sheet with new updated 2013 prices.
If I could get the digital copy of the book then I might could make a database of the machines and we could post it here with someone having the means of updating the prices based on sales.
Just a thought.
