FeedDemon is now free.
Mmh, worth investigating... I even bought it once (three years ago). Does it still sync only with NewsGator with subscription etc? I might go back to it only if it supports Bloglines or Google Reader, as it would only be for my work machine.
UPDATE: indeed it does only sync with NewsGator. Ah well, I'll stick to Google Reader then... I wish a KDE app would sync with it, aKregator is currently only a local (and very basic) tool.
