Shareaza, Gnucleus and Phex are free of any "unwanted" crap.

All these clients are able to connect to the Gnutella network. Shareaza is also able to connect to its own network and the donke network, you can also download torrent files.

The "free" versions of Limewire and Bearshare contain additional crap... so you have to pay for them but I really see no reason for this because the others are free.
