.org, .net, .info, .biz taken but .com available?

[DNbuy]

I remember quite a while ago using a service or software that would allow the user to find all domain names where the .com was available while the other extensions were gone. Does anyone know where I can locate this?

Thanks in advance folks.

LocalWhois.com used to do this, but only with the premium service. Not sure if they still offer it or not. domainsbot.com may be able to do this as well in custom searches, but I haven't been a member for a few months there.
