YouTube - Single Transistor FM Transmitter
A new video on YouTube shows step by step how to build a single transistor FM transmitter for about 90 pence ($1:50)
The design is based on the 2N3904 transistor and it is made on a board about the size of the UK two penny coin. It has a range of about 200 metres.
Watch the constuction video..
For the parts list see the YouTube page

Remember that the regulations regarding the use of such low power transmitters varies from country to country and it is recommended to check your national regulations.
