3.5 is dead. Long Live 3.5. This is probably, bar none, the best 3.5 purchase I have made. Sure, you can get the SRD online for free, but a nice complete PDF package is a pleasure to have.
Complete and well done, it does a fine job in presenting the 3.5 e rules.
Pricey if you already own all the source material, but a good investment if you play 3.5 at all.
