Aside from that I would say these are the majors:
Inktomi, Teoma, FAST / Alltheweb, and Altavista, but really, those last 2 are the same since Overture bought them.
Many of those have international reach, and of course, Google is free. Then there are directories, and pay per click.
But those are 2 more issues. :)
Hope that helps.
