I added a page to my website with links to websites that have LiveJournal Icons for the taking, as also the links to the LiveJournal Communities interested in icons.
SO if you are bored / dissatisfied with your present icon (or the lack thereof) you could use these links.
Free users can’t do a directory search. That’s what I did to get the list of LJ communities interested in “Icon”.
Hope this is helpful.
