I really like duck duck go. I just wish they would register ddg.cm so I don't have to type out the whole url. I would register it myself and forward it if it wasn't for the fact that cm registrations cost nearly 100 dollars.
If you bookmark any website's search results page, you can add a keyword and edit the bookmarked URL to include a printf-style %s placeholder. When you enter the keyword plus some string, Firefox opens the bookmarked URL, substituting your string for %s.
I've moved to using it as my default search provider. I'm using it well over half the time and if the results aren't great I add !g to the end to get google's results.
