Overture still has some value perhaps? Data from jan 2007, but generally type ins are pretty constant on many domains unless something changes (ie site close to it promotes heavily)
check out OVTMatcher.com - this is a new tool we created, provides data for January, February and March 2007 OVT w/extension, and also provides access to OVT scores without extensions to over 100,000 keywords
The data is 1.5 years old though, how much is actually still relevant? I wouldnt base my research on old data like that personally.
It is one of the only ways to locate traffic domains in the huge daily drop lists. Bidders at SnapNames, NameJet and Pool use this tool all the time to pinpoint domains with potential traffic. Of course, after you find them you should do further research to see if they still have traffic, like scanning for alexa rank etc. You would be surprised how many people love this tool.
