My favorite search engine is Google.
I follow one motto:
If it's not at the front page, my search ends there.
Sometimes, I have to use other search engines too if I can't really find it in Google (yes, I've looked over page 1 too
For images, I use Flickr (if it's a search engine) because I just don't want to use Google Images.
Hmmmm.. GooYahIng.com saves up lots of time and efforts too.
Cheers! (Cool! My first post on the board!)
