Actually, WinMX has no spyware. It's a little harder to figure out than Kazaa and eDonkey, but once you get it configured and locate some good OpenNap Servers, you can find anything on it, and you have a lot more control over things. Speeds vary depending on whether you find it on the OpenNap or the WinMX Peer network. Often, though you can dig up a nice T3 on the OpenNap and...... I haven't touched Kazaa or eDonkey since I figured out the OpenNap.
