This is a steal at this price. If just a couple of these encounters are used in the game, or you use the cool maps, you will get your money's worth as you and your players have a blast.
There are some really fun encounters in this product, and they are self-contained. You can run them as one-shots, but easily add an overarching plot to them. Those jackalweres? They are in the employ of the big bad gal in your campaign. The gang of thieves? A front for your villain. The ease with which this can be done makes the product even more useful.
Each encounter is nicely laid out and has scaling options (often covering APL 1-10). THe maps for the encounters are great line-drawing "battlemap style" art and work well for all kinds of situations. I think many DMs might pay this price just for useful maps.
