"Alien Vault" Book by Ian Nathan

Hey everyone, Just curious to know who owns this and what they think of it. I've been considering buying it online, but recently a copy turned up in a local bookstore and I had a chance to leaf through it. It's interestingly produced, with all of the pouches with the fold out blueprints and storyboards, but I kind of felt that there wasn't a lot of new / revelatory information in there. Lots of pictures, but I think they are mostly ones we have seen before as well. I also know that some of the reviews online are mixed. Just wondering what people who own it think. Cheers!
