StudySpanish.com - some free lessons
StudySpanish.com offeres a good amount of free learning and lessons with a full language course available (only $155 as of Nov 2011).
Full pronunciation lessons are right on the web site, and the stepped audio format is nice. Vocabulary lessons are limited to about half the words for free, and the other half (and advanced vocabulary) are in the paid program.
Buying the program also gives you 12 months access to all the premium materials on their site, including a podcast (first two episodes are free).
I think you can get quite a bit of milage out of this site, even if you don't buy the course.
