Back when the first edition of the book came out the products were worth that.  The copy of DAZ Studio given away on the disk is last stable release of DAZ Studio version 2. 

The version of Cararra is 6 Pro.  The current release is 8.5. 

Hexagon is the same but then that should tell you something.  It was part of the giveaway for awhile and is now sold at a far cheaper price than when the book was released.

As for the V4 and M4 content, it's the Complete bundles.  These are bundles that sat between the Starter bundles and the Pro bundles.  They have a few more items than than the starter bundles but less than the Pro.  DAZ dropped them from the store some time ago.
