Star Wars best ship's book for Xwing TMG

Hi! I know the Star Wars wiki and diving through millions of Internet both official and fan-made pages is probably the best way to get accurate information about our game ships, but I wonder if someone knows which is the best printed book for technical and historical information to use along with our miniatures, to add more immersion into the game I found this book, (it covers the first filmed trilogy)

and after some research trough reviews & opinions it seems to be the best one and worth it (you can find it for about 10 USD shipping included to Europe). THANKS!!!!
