I'm afraid that I haven't followed the responses to the topographic map inquiry as closely as I might have done, but I don't remember anyone mentioning what I think may be the most convenient sources for topos. Our university library maintains a collection of topographic maps, many of which circulate, and I believe that other university libraries and even some public libraries have similar collections. In our area, many sporting goods stores sell topographic maps. I don't suppose that their coverage is exhaustive, and it wouldn't surprise me if they skipped the urban sheets, but it's worth a try.
