I have just finished up a b&w series of classes and have really enjoyed it.  It is pure magic to see your print come to life.  I don't think that digital will completely replace film.  I just think it is a different medium.  Granted the camera companies are trying to "force" digital down everyones throat, I think that there are valid reasons for film.  It will definately teach you to be more precise in your picture taking as reshoots will lead to added expense of film.  I used Illford HP5 Plus 400 asa film (found at professional photo stores......not at walmart) and had and continue to get excellent results from it.
