I'll second Jeff's suggestion. I bought the book early on and found it informative and useful, although reading about the number of things that could be wrong with a 150 gave me pause. Since I haven't bought a 150 yet, you might say that, to date, the book has saved me thousands.
Mike, the author, will even answer email regarding specfic questions you might have after reading the book. Well worth the bucks!
