In addition to the suggestion by JeffH, I would also recommend the following: www.baument.com (A few free and many very detailed at a very reasonable cost) www.chemicalstudios.com (I especially love the comicbook store) avalon.viewpoint.com www.poserworld.com (A few very unique building environments built in Canoma) I am sure that there are more but those are the places that readily came to mind.
