roomba 550

The Fifth Element: money

For my birthday, my uncle gave me his old roomba 550, knowing I would enjoy fixing it and putting it to use. He got that right, but unfortunatley, the parts that I need add up to 85$ plus shipping and handling, but I have to get at least $70 for it. Allowance is out of the question, because I don't have any. If anyone has any sugestions, please tell me. By the way, does anyone know anything about hacking roombas?
