need models

i m lookin 4 some models ( i mean houses, trees etc…) which could be a set of vertices or anythin else that i can just add to my scene. is there neone who has any? or could neone direct me to a site that offers somethin like this.

what im tryin to do is to create a surface from a DEM (digital elevation model) and provide the user with a few models which he/she could just drop it in the scene.

thank u

Got some free, lowpoly models…
