Another option for domain searching
http://www.namedroppers.com/ is another option for domain-name searching (and might have a future as a caffeine equivalent - looking at that yellow background in the morning is almost as good as a cup of coffee.) You can search .com, .net, .org, and .edu domain names keyword. Enter duck in the search box and you'll get a list of domains that contain the word duck. The advanced search ( http://www.namedroppers.com/ advanced.html) gives you the option to exclude keywords and specify a domain name length (from 1 to 63 characters.) They also have a form you can put on your page. Worth a look.
