Worth mentioning that NZBget is no longer in development. It still works but there is a fork out of a new client someone is developing. I can't recall the name but easily findable. This would be the equivalent of your torrent client.

It's nearing year end and you can get end of year deals soon on providers and indexers so off hold off until November\December. I think I got a lifetime NZBGeek membership last year for like $100 or something. It was my first time doing usenet but I actually switched my instances to use usenet indexers first over torrent indexers its that good.
