I use two others..
Shareazza It has access to a LOT of content...but the DL's are awfully slow.
I also have KaZaa Lite Revolution...
It took me a LONG time to find a FREE download of this program...KaZaa has switched over to the Dark Side and is now a Pay service.
I have a friend that uses LimeWire..and he says it works pretty good too.
