I have found a couple helpful Domain Name Search Engines.
What I look for is a system that will let me key in keywords and it will find Available Domain Names with those keywords. Two such Domain Name Search Engines I found do a good job of giving results, even if the results are not exactly what I am looking for sometimes they can help me see some combinations I would not have thought of.
Just type in some keywords and let them show you Registered and Available Domain Names.
If nothing else, a Domain Name Search Engine can be a lot of fun to see what type of names people have chosen. Trust me, if you think a name is too bizarre, it is probably already taken.
