Another edit: I don't know how I missed this one, I think it's because it was posted so early. There is a neat, free downloadable adventure called the Tower of the Red Angel here at ...and the Sky Full of Dust.
That's three free adventures right there!
Make it four, and I really, really recommend this one, the Forbidden City of the Black Idols (Taqat) by Nicolas Senac. This is pure, undiluted Swords & Sorcery here -- it rings like R.E. Howard.
