If you're looking for a general introduction/remedial/refresher resource, you could do a lot worse than the MathTutor series of DVDs. They're not particularly cheap, but they are cheaper (and quicker) than full-scale courses. You would probably need to find a source of exercises/quizzes/tests to reinforce the learning though - I would expect any university entry-level text should give plenty of those.
