Best Free Skype Recorder

I am looking for a program, freeware or shareware, that will allow me to record 30 minutes or so of Skype calls to MP3. Any recommendations?

I don't use Skype, but I am pretty sure it can record whatever's going to your sound card.

Already have audacity....will try and find how to sync with Skype.
