is there a domain engine, that like can help you with a domain choosing...right now domains are becoming slimer and slimer, the .coms are anyway...

I think it was http://www.nameboy.com/ that offered the kind of service that you're looking for..
http://www.register.com/ has a little thing too when you look up domains. Check them both out.

I'm sure there are more out there but i found this one that works pretty good. Just enter in keyworks and it'll try every possible combo
