I've always used Google as my search engine but recently saw an interesting post (on a gardening message board) about a small charity which linked to this http://easysearch.org.uk/
You can choose from a list of charities and then when you search, if you select one of the sponsored links, the charity gets some of the money.
Aside from that, it combines Yahoo, Ask and Bing. It seems to pick up some family history stuff which Google doesn't rate so highly. Could be worth a go sometimes.
I love Google but I like to give the little folk a shot too
