I broke down and got an I-pod (I have a Zen too, but use the I-pod now) So I use I-tunes for podcasts. I think what you want depends on your interests. I really like "wait,wait don't tell me" it's a "game" show from NPR, current topics, but in a fun way, and they have celebrities take "quizzes" that are really funny. But to each his own, and you may or may not like that one.
I saw a spark blog about a podcast from some diet bloggers that sounded fun. Just look around and download some, if you don't like them you can just delete, and if you do, you've found your gem!
