I must mention Other CB Clients (linked from the Chatterbox nodelet), which mentions a lot of chatterbox clients.
I use a variety of clients. Apart from cbstream, I sometimes look at some of the cbhistory webpages (usually Corion's CB60, but if I somehow need more than an hour, then belg4mit's cblast35 or Tanktalus's node). I also use the cbstream nodelet, and the two chat input boxes in my Free Nodelet, one of which is pre-filled with a link to the node I'm viewing, and one that loads to noisy sunset so I don't have to reload the page I'm viewing.
