DomainChecker

DomainChecker is a domain name checker which uses WHOIS queries to find taken, free and expired domain names on over 100 domain extensions. DomainChecker lets you find domain names in many different ways. It can search the web using keywords of your choice, generate domains based on keywords, import domains from a file, extract from fileformats used by Snapnames.com and Pool.com, and it can also generate misspelled domains.
