Developing your own B&W is cheap and easy. You need a dev canister, get a double 35mm, so you can do 2 35mm rolls or 1 120 roll, and reels. You can find these cheep used. Find a closet to load the film, and the rest is done in the light. Unless you plan to do a few roll a week, I wouldn't recommend buying chemicals in bulk, they go bad too fast. With 500ml bottles It's about a buck to develop a canister, ie. two 35mm or one 120. It's better to do youself for the cost, and also because you can control the contrast of the negs. Adjusting the exposure in the camera effects the shadows more, while dev time changes the highlights more. Pretty soon you'll have a dedicared room and an enlarger.
Good luck, Ryan
