Heh, I have to agree that PDFs are the way to go for this.
If you want some free tiles look up Warhammer Quest on Google, here's
one site for the game, there are several others, with some very different boards.
I am more fond of three dimensional builds, enough so that I am considering the World Works Dungeon Linx set shown above as a floor for their other sets.
I am also trying out Fat Dragon Games recent releases, they are simpler builds, and might be good for my summer children's game at the Festival for Creative Youth. (I love my summer job. The kids are bright, active, unpredictable, and energetic.

) World Works and Fat Dragon take some very different approaches. (World Works are more detailed, but the builds are a lot more involved. Fat Dragon tend to be easier builds, and perhaps a bit more solid, but with less detail. Both are good.)
