need podcasts

What are you favorite podcasts?

I ditched my XM radio for now... In the car each day I listen to the PennRadio podcast. Problem is, it's 45 minutes long, but my drive each day is 50-60 minutes.

I have a few others I like (here and here) but they are updated very infrequently.

Most others I've found are not much better than the "Brad & Britt lets-pretend-we're-lot-leftists" show or the "Bill & Sherri in the Morning show" AKA "the Survivor/American Idol rehash show".

Please help me avoid these!
