GoDaddy.com has very good administration of domain names, so if you want to use them they are cheaper and can serve all your domain name needs.  DO NOT get their hosting - it is a nightmare - but the domain name service is very solid.

When you receive your domain name account you will need to directly any you wish to use with this account to:

ns1.alnma.com
ns2.alnma.com

If your not sure what this is or need help we will do this freely for you.
