Paizo's own products are I think among the most inventive of the hobby in terms of quality and actual use value in a game.
For instance, in the Game Mastery line, you have the Item Packs which provide you with good looking, practical cards to hand out to your players during the game, thus enhancing the visual and material appeal of the session while increasing the overall organization of equipment and magical items.
The Dark Elf Sanctum and all the Compleat Encounters follow this same logic: these are made to be used. The short adventure/few encounters included here are scalable to any character levels. The text is clear and uses ideas that are easily dropped in any homebrew campaign.
The miniatures are absolutely awesome. I loved the horned demon so much I use the miniature for my own character when I play the game. The sculpt is gorgeous, the bases are large and well textured, part of the miniature, which changes from the crappy plastic bases so usual these days.
A plan to assemble the four tiles of the battlemap would have been appreciated, but this is really a nitpicking, to be frank. Plus, it in fact has been taken care of in later Compleat Encounters.
Really amazingly cool for such a low price. Great.
