Wow, Deamoclese... that's just freaky.
I, like a few others here, buy loads of adventures. What I prefer is "generic" geography - in other words, I'm can put it into any land-mass or world with few or no changes.
I also am *very* picky about the maps. The maps have to be good (no computer-generated maps) and absolutely must have grids for interior locations. No grids = no buy.
I also like mega-modules since I get a lot of mileage from them. (And have been eagerly awaiting Black Sails Over Freeport for a while!)
For me, level is *not* a concern at all. Sooner or later my PCs will be of that level, so the level of an adventure is a complete non-issue.
Further, I'm happy with any theme (in fact, I buy all sorts of adventures so that my players can experience a variety of themes), so I would buy any (as long as they meet my above criteria).
Finally, I dislike stories that are "way out there" or too weird. Dungeon Magazine adventures are about as weird as I am willing to accept (and even then I groan a few times when reading them).
