Personally I thinnk that the search method in Camino has Firefox and Safari beaten hands down.
Just start typing and as long as you're not in a field on the page or a toolbar, the search starts automatically... Then just command-g to skip through the hits...
Uh... that's how I search text in firefox. You just have to activate it in Preferences->Advanced.
It's not on by default because being so different it could be confusing for new users.
