Something like 10TB of movies, downloadable clips, around $10-15/mo and movies still playable after cancelling subsription, so you have the option of joining downloading everything and quitting. DL speeds differ depending on your location, but in the states, got about 3-500k/sec on broadband cable. Now overseas, so its around 50k/sec.
If you arent looking to pay and dont care about DL speeds, there is always limewire/torrent. |
