This tome has proven to be quite useful for my games (3.5 in particular, but should work fine for Pathfinder). It's by Necromancer games (probably now OOP) and is an excellent tool for the harried DM. There's been a couple of times that I didn't have time to properly prep for a session, or the party went in a totally unexpected direction, so I made a few rolls and voila' I had a complete evenings adventure!
