I also use Azureus as it is the best BT client (IMHO)-I have tried a bunch.
It also works on both my pc and mac (a plus). ALSO Azureus contains NO spyware.
To use Azureus you need.
1. Azureus
http://azureus.sourceforge.net/download.php
2. Java Runtime Environment
http://www.java.com/en/download/manual.jsp
Do the following:
1. Install the Java Runtime Environment
2. Reboot
3. Install Azureus
This is all very plug and play ez. The only challenge for some people is opening up the correct ports on their router as Azureus and all Bittorrent clients typically run on ports 6881 - 6889 (TCP). If you need help with this simply google your routers name with the above port address and hunt around.
Good luck and have fun.
If you like Anime try: www.boxtorrents.com they have a lot of good movies, manga ect.
