Modular 3D Dungeon Tiles

This looks really cool: http://p068.ezboard.com/fhirstartspostyourownpictureshere.showMessage?topicID=1739.topic.  Modular 3D dungeon tiles to lay out a dungeon as you move through it with miniatures...

Hirst Arts sells molds and provides advice on just how to do this.

Or one could go the much cheaper route: print out and glue together the tiles found here: http://www.enworld.org/CrookedStaffProductions/page8.html.  For instance (there are a bunch of other ones, too):

Also useful (and that's why I'm posting it here): A PDF of 1/4" Isometric Mapping Paper.

Paper = easier and cheaper to store.. The other setup looks like the Druids Heroscape collection.

I completely agree that paper's easier.  It also allows the DM to put together sections, like corridors or rooms, and just plop 'em down as the characters can see them.
