I picked this one up from Phil Bradley’s blog. Think of it as Turbscout with lots more search engines and lots more types of search. The search tools are organised under tabs such as Web, Images, Reference, News, Blogs etc. Click on a tab, enter your terms and click on each tool in turn to run your search. I particulalry like the URL tab which, amongst other things, finds pages that link to your known URL (backlinks), runs a Whois on the domain name, and finds archived copies of the page. And there is a custom tab where you can build your own collection of search tools.
