Unregistered Domains by Keyword, hunter.

http://www.keyword-domains.org

Its a lot like Domain Hunter, but doesnt waste time printing out the registered domains, only the unregistered. Seems slow at the moment, but has been working more reliably for me than domain hunter.

This tool appears to query directly which is a bonus.

 

hmmm, does it work with safari on Mac?

Im just getting an empty form box when its found the domains.

 

I like this one from a DP member:

although it doesn't do .org
