A third book would be great. What ever you do to it, I would buy a couple. If I could make only one change to a possible third book it would be to add more photos. Maybe a couple per page would make me happy. I know it is more work, but I would be willing to share any of my pumps for the book. I would send you some over all shots of them and if you wanted to use any I would move the ones you chose out in front of my garage with the door down so there would be a neutral backround. That should help a little in being able to use the picture.
