I need some sort of program or website to help create and check domain names.

I need something where I enter a bunch of keywords and it makes a list of suggestions and then checks the availability of each name.

There is a good tool at http://homepageuniverse.com/names/creato... that offers the sort of functions i'm looking for, it's just a bit too restrictive in the creation part.

I am also interested in any programs that will check all combinations of a series of letters and numbers to see if they are registered.

Most informative answer with the most links and relative information gets the points!!!

Try domjax.com and pcnames.com, both rather recent.
