Useful Resources for Spanish Learners

I have taken two 10 week Spanish evening courses, Beginners and Beginners plus with Cactus Language Training in Brighton. Classes are fun, have no more than 8 students and are taught by native speakers. The good news is that they are now offering free iPod downloads with Spanish courses, which helps me to practise my language outside the classroom without paying any extra money.

What can be a better way of learning a language than with a native speaker teacher? I have tried learning in different ways - through iPods, books, CDs etc but was always difficult to push myself to learn in a disciplined way.
