What about reg2c.com
They have really good offers for the domain names for .com,org,net,biz and info.

for .com the prices start with6.99$ with 100 e-mail account is free.
and .info is for 4.90$ as far as ı checked.

And I saw they have some campaings like if you transfer your domain orif your register 3 domain names at once they will give you a free hosting pack for one year! cool isnt it?

I'm not sure what you really looking for but maybe you can find what you need ,there.
