WEBMASTER TOOLKIT - http://www.wmtoolkit.com

Webmaster Toolkit provides a variety of free tools for webmasters including whois search, broken links checker, search engine indexed pages report, link popularity and ping tool as well as a search engine position tool which can simultaneously retrieve a site's position in the search results of the 4 search engines(Google, Yahoo, MSN & Altavista) for any keywords you choose. It is a fairly new and simple site but I hope it can be useful.

Thanks for looking,
