IPodderX Lite will reliably crash in 10.3 when you:
- try to delete a subscription while listening to another
- try to delete a subscription while it's refreshing

It hangs up considerably when you do things like:
- browse the directory while you're listening
- change anything while you're listening

Otherwise, it's got a great interface, although it shouldn't take 3-4 clicks to hear the audio feed on a podcast -- it should only take 1. I think IPodderX Lite is designed to help you be patient. Not too bad for free, by the way!
