I see Paul beat me to the Instant Domain Search plug. Here are a couple of other sites I found useful. http://www.nameboy.com http://www.nameboy.com (takes 1 or 2 words and generates a list of potential domains related to them.) http://www.makewords.com http://www.makewords.com (A little complicated, but if you figure it out you'll find some pretty decent domains available. It takes 1 word and generates domain names that include that word, along with a prefix of suffix that comes from a theme, like actions, education, business, etc.)
