I signed up for a one week unlimited free trial (that doesn’t even require you give your credit card information) from http://www.pureusenet.nl/en, and I downloaded the free usenet client SABnzbd. With that, I was able to download this whole thing in about an hour with an average speed of around 10 Mbps without paying a cent.
I found the exact same trial! downloading now. Try these:
