This is probably one of the best and most thorough collections of items for PC's and NPC's alike available. It includes a section on firearms should you want to include them in your campaign. The small drawings throughout, I believe, helps you visualize your tools of the trade. No less than eight tables of slotless equipment - four pages of random item generation. Altogether, 400 pages of crunch for both players and GM's. There are almost too many to count pages of random items. Each section includes a table of items and costs. The book includes both a good Table of Contents and a comprehensive index.
This is another hardcover book from Paizo that should be indispensable for GM's, and close to indispensable for players. One of my higher recommendations.
