What Podcast App do you use?

I am a huge fan of podcasts and have been using the iPod/Music app on my iOS device to listen to them. I do not have huge issues with it. However, I would like to look at alternatives to further personalize the experience.

My wishlist includes:

  • be able to list your most favorite shows and download new episodes (manually or automatically)
  • not have to worry that it will sync with itunes when i sync my device
  • be able to download and listen to podcast all in one app (right now I use the iTunes app to download and the music app to listen)
  • free? :-P

Would love to hear what your experience is with the other apps out there and what your recommendations are.

...or maybe the iPod/Music app on iOS is the best out there?
