You're all wrong, alt.binz is garbage.
http://sabnzbd.org/ is the best usenet client there is. It runs as a daemon, has full RSS support, auto-categorisation/par/unrar support, ssl and if you get the browser plugins for firefox/chrome then it integrates right into popular nzb sites like nzbmatrix and binsearch.info.
Seriously, it is fantastic, and still supported (unlike alt.binz) and free.
