Under $250 ? Some old and heavy used GITZO comes to my mind. For example here in Tokyo we have some used-equipment shops who sell mostly broken cameras, lenses and cases for parts but usually also have a good assortment of former professionally used heavy tripods. I have seen a couple of LF suited in your price-range here so it might be worth looking for this kind of shops where you live.
EDIT: I just realized that your location is NYC. Well, NY is not such a big place for photography or design as Tokyo is but I think you should find something. 🙂
