I'm trying out gPodder right now and so far I got mixed thoughts about it.

On the Pro-side:
- Nice feature sets such as choosing what media player, etc.
- Rather quick download of new episode.

On the Con-side:
- It takes a LONG time to add a new podcast / get the episode list ... a LONG TIME.....
- It seems to be a sluggish application in general often becoming kinda unresponsive - in particular the Preference window when opening it from the status bar icon.
- I tried for 20-30 mins to find a way to set the application to keep X number of episodes but could not find a way to do it

If only penguintv would even run for me I could try that one out....
