Any tool for finding relevant adsense sites?

In Google adwords, there is a feature where you can select the sites on which you want your ad to appear more often than other sites. I am currently testing that feature and hence I am looking for relevant sites which run google ads.

I would like to know if there is any tool which can fetch adsense sites relevant to my keywords. Thanks for your comments.

there is something called adsense finder form chris of dayjobkiller fame

I don't have it or even know if it;s been put on here before

try searching here for it

Thanks Oscar for the info. I googled for adsense finder and could find a free version of adsense finder (not by chris) at portalfeeder.com/adsensefinder.php. This software works like a charm.
