Domain check tool

[cush]

Hi,

does anybody know a tool that can do the following:

- generate domain names of a given base name
- plus keywords in a list
- and check them for beeing registered already

I.e. I want to give 'blubb' as base name and 'key1', 'key2' ... 'key5' as additionals. The tools should now generate domains for selected TLDs like blubb-key1.com, blubbkey1.com, blubb-key1.net, blubbkey1.net and so on.


The more features the better.

Anybody?
