Overture & WordTracker get their results from different sources, so it's actually good to look at both. It's important to note, too, that Overture shows you the approx number of searches per month, and WordTracker shows you the approx number of searches per day.
It is said that Overture's data is inflated due to webmasters using it so frequently for research. That, combined with the singular/plural issue, makes me double check results at WordTracker.
As for Alexa, it is a completely inaccurate tool - not one taken seriously by site owners & SEO'ers. In order to find out how many backward links a page has, you need to use the "link:URL" command in Yahoo Search.
