Other site I found useful is Nameboy. You give it terms and it tries to find combinations of them that are available. It's pretty slow though, so I think they are not using a local database but are instead doing something expensive to check each combination. I have my own one too which checks expired domain name listings for promising looking stuff that will become available soon. I can crosslink if you like, but only get 1000+ uniques per month. Not making any money after the expiring domain registrant affiliate programs were closed.
