I got started on developing my own BW stuff by taking a class at a local high school roughly two months ago. It was one of those night classes for adults; you normally get a course listing in the mail. Cost me $180 CAD and learned plenty about BW; I knew nothing about it prior to joining.
Now, I've got my own dark room set up in my basement and am having lots of fun making prints!
The best thing about this method is that you get to try hands-on before you actually make a commitment to buy all the equipment and supplies.
