Great product. Good scan and indexing. The handbook is just fantastic! A lot of background and new careers. An hint for the game masters: don't let yourself be overcome by the power of the new careers and weapons. In a Dark Heresy campaign you have to reduce this things, or the other player (the ones with characters taken from the core rolebook) will be really disadvantaged! Instead you can give some extra equipment to the other PGs.
Anyway I love the first chapter, the one with all the background! And Faith and Fury, the one with the faith powers! I haven't already read the last chapter, with all the hints to play an Ecclesiarchy Campaign. It seems to be a great source of great ideas for roleplaying!
