For all you budding podcasters out there who are evaluating your tools and techniques for recording your audio, I think you may want to reconsider until you check out Ubercaster. (There's supposed to be an umlaut above the 'U', but I have no idea how to render that. Use your imagination: pretend it's there.)
Ubercaster is the slickest piece of Mac audio software I've seen to date. Not only does it appear to be quite powerful, but simple and intuitive. I know that I'll be substituting my current setup for this software as soon as it's available. No word on pricing yet, which could change my mind (but I doubt it).
