I use WinMX. I tried downloading KaZaA, but it says that I\'m missing something that\'s neccesary to run it, and it just doesn\'t work. WinMX works for me, seems to get the job done nearly every time. Of course, I use AIM transfers a whole hell of a lot, too. Songs, files etc, AIM seems to work very, very nicely.
