Search expiring domain names and NameJet, Snapnames and GoDaddy auction lists to spot a bargain. This list updates daily and provides and is completely free. I've used it for the past few years and picked up some great names. I no longer have time to be a full time domainer so I'm making this domain auction list scanner available free of charge
The search term query data that the database runs from is pretty old and the algorithm I wrote years ago (when I was still learning Perl) is basic to say the least. However this tool has led me to a few real gems in the past.
I wrote another domain scanner which will give different results since it is base on a different keyword database
