Why not develop it at a shop? why black and white? and why in god's name don't i just buy myself a digital camera??
Because i like to throw off the chains of digital imprisonment and make something REAL!......(this is a lie)
The reason i started developing b&w at home is i couldn't find any shop that would do it, and after speaking to some nice people in a camera shop i ended up buying all the stuff to do it myself ( for only about 20 pounds), and after my first film developed i got a bit hooked on it, also with practice you can have greater control over how you negatives turn out (i haven't really practised enough to do this).
B&W film is a hell of a lot easier to develop than colour (so I'm told) and i think it looks arty-er so pretty girls will want to hang around with me/make sweet love with me more (........yet to happen)
Also a film SLR can be bought really cheaply and you can get some cool looking results (i like cameras from USSR or east Germany, any camera that outlasted a nation has got to be good), and i also don't have the money for a decent digital camera.
Slight disclaimer- I don't claim to be an expert at this, this is just what worked for me and i was happy with the results, i realise there are other step you can take such as using a stopbath ect. that might produce better results so YMMV.
