They have a service where they have registered heaps of domains and then lease subdomains for a next to nothing. You can get just an email name, or email/website package with 5 mb space. Ususally big enough for startups but no cgi etc.
They have Family names and generic Business names so you can usually find something suitable. And no problems submitting the subdomains to search engines.
I use them for some clients but am not affiliated with them.
