Digital Terrain Model vs Digital Surface Model

Just wondering if anyone out there knows of a good source of DTM data? Data sets such as SRTM are great for what they are, but I have a specific need of a set that models the base terrain surface, not the reflective surfaces. I'm hoping to avoid a set that returns tree-tops, building-tops, etc as elevation.

As far as I can see the mainstream free sets, such as SRTM, ASTER, etc are all DSM?
