Not sure how you can get more reasonably priced than free!
I have three of the skipper bob publications. They are a good value.
But if you have an internet connection, I think the activecaptain site is much more useful than a book. It adds the visual aspect of seeing where you are, and where you are going, and all of the navigational issues between here and there.
I can't really say how accurate the end user supplied data is every where else, but the info supplied for the galveston bay area where I am at the moment is very good.
