I like AAW Games modules. They all take place in the same area but there are several different modules you can choose from for each level. There is something for every taste. They are well written and provide good structure for a GM but leave room for improvising. The adventure paths and path finder society mods are cool but I don't like being locked in to a specific path for 15 months or for 20 levels. I pick and choose the AAW Games mods that I think my players will have fun playing and there are a few that build off each other if they particularly enjoy that setting. I would encourage you to check them out. As a GM I enjoy the freedom of getting to pick and choose what missions come next and not having to do the next quest in a adventure path or the next society mission.
