Where a site ranks on google based on specified search terms

Is it possible to find out how far back your domain is on a google search without having to constantly keep clicking next?

There are a few sites:
http://www.mypagerank.net/
http://www.mygooglepagerank.com/
http://www.googlerankings.com/
http://www.google-pagerank.net/

google-pagerank.net is now redirecting to google.com ?

http://www.googlerankings.com/ is the best
it also do MSN and yahoo
but requires the google API key
