This is basically my favourite published TSR work ever. I love the puzzles, mood, setting, coherence, goals, everything.
However there are flaws with the pdf. No one corrected the OCR, so there are the typical errors like Ld4 and HDLL, but more importantly the map is very awkwardly cut into pages which makes it difficult to read in spots.
I've cleaned up my copy using ABBYY software and by scanning my original map, but really if WOTC is selling this they can do the same.
