Learn Hebrew Pod - Podcast Hebrew Lessons
Ran across this site today and think its an interesting choice. They have some free podcasts for download too. I had to laugh - they teach the way I talk - The 1/2 in English, 1/2 in Hebrew. I love this though because for me - it shows me the way to conjugate the verb - you hear it, then they reinforce it. For some it might be too distracting to hear the english though.
