If you're in London, you might want to visit the Waltham Forest bicycle recycling scheme on a Saturday. I have a friend that works there sometimes. You can get an inexpensive bike and convert it. Plus, they let you use their tools and workshop to work on your bike if you want to make any changes or whatever. I think they only charge £3 or something for that, and they have all sorts of old parts lying around.
