Best startup landing page service?

What's a good site that provides a simple landing page (that you don't have to host yourself) to gather pre-launch email signups for a site?

Something I could point the name servers of my domain to relatively easy. LaunchRock is invite only it seems. Is there anything public out there?

EDIT: To clarify, I'm thinking more of a "beta, pre-launch" landing page. Something that briefly teases what's coming and says "sign up to be notified first."
