Query: Truly outstanding, and it pays for itself

This is one of the finest books on PC troubleshooting ever written. Each chapter contains a list of symptoms, suggestions, and solutions in an accessible format, helping a technician solve even the most obscure hardware problem quickly. Any book that keeps you from looking like a fool in front of a customer is worth its weight in gold (and it hasn't let me down yet).This book is also good for aspiring technicians, presenting exhaustive (but not overwhelming) coverage of topics you are sure to see on the A+ or CST exams. The author is kind enough to include useful diagrams and historical tidbits throughout the work, making the arcane comprehensible and the boring bearable. How many computer books can you think of that accomplish such a feat?Mr. Bigelow, if you're reading this, I would like to thank you for producing such a wonderful book. Suggesting it to others is the least I can do.
