World dance new york has put out some decent instructionals, and their dvds are around $14 each on amazon, or from ocean state media (they also run deals on shipping and such if you are buying more than 1).
Also, check to see if you have a local middle eastern dance association near you. Most of them have a library of books and media that are really inexpensive to borrow from, and memberships are generally well worth the money spent. It is also a good way to preview titles before you invest in buying.
