Hands down, this is my favorite podcast on the net. Kusala is an amazing, insightful, funny and loving speaker, one of the few people I'd hug on sight, if I ever had the opportunity to meet him. His podcasts are also *good*, always interesting, with thought-provoking subjects, wonderful interviews and terrific class lectures. "Urban Dharma" is an excellent podcast for the beginning Buddhist, but is also for the spiritual seeker of any religious, philosophical or spiritual path.
These are also easy to listen to, recorded well, with good volume and hardly any background noise, static or fuzz. He will also let you know at the beginning if the recording isn't as good as usual. (These have pretty much been the earlier ones, before he upgraded the microphone.)
