SmartWhoIs
Designed for network operators and security professionals, Smartwhois, makes an ideal tool for domainers to quickly check on domain name availability. Its batch mode and tunable delay settings make it easy to dial back the frequency of queries to match the policies set by the registry operators for the generic TLDs and ccTLDs.

BulkDNChecker
Great little tool that got me started and I still use it when I need some quick and dirty checks done. Limited by the short list of TLDs that it supports, and I have experienced problems with it crashing on low bandwidth connections.
