That's what bookmark is for. `Google' is not easy to type either, at least compared to `bing'.
I put DuckDuckGo at position 3 of Safari's bookmark bar (position 1 being bookmarklet from instapaper and position 2 being bookmarklet for my posterious blog). Then I could just press command-3, and type `!w Al Franken' or `!w faithful place' or `!python tempfile'. Pretty sweet IMHO.
