A good alternative (apparently - I'm yet to go through it) to 6.001 is CS61A from UC Berkeley. There are Webcasts, lecture materials and assignments available for two types of CS61A - a slightly older (2008?) class taught using Scheme/SICP, and a newer (present day) class taught using Python/SICP-based textbook (available free online). So CS61A may be for you, if you are looking for a more modern and/or complete 'downloadable' SICP course.
