Personnally I used mechanize (which was firstly a perl library before being coded in python) some years ago and it was simply awesome. It is not only a "scraper"; you can put informations on websites, because you can emulate a whole Web browser... However It does not seems to be still under active development, so perhaps you should continue to use beautiful soup which just works fine.

Best.
