I like the blue book for accurate price comparisons. A certain model can be worth 2-3x as much as a similar one, the blue book can differentiate between the two.
The gun traders guide is a good quick reference, with pictures to go by. Still, the blue book can be off due to location, availability in your area, and market ups and downs. Look what happened to semi auto rifles in the last year as a prime example.
Decide if he needs a quick reference, or an accurate comparison that can take some time researching.
