Ask HN: Creating Animation Movies for business use - free/cheap

Hey all,

Am needing to create a quick info video for a landing page. I've checked out a few sites and they offer sweet products, but are a bit pricey considering I just need one video.

Was wondering if anyone can suggest free or cheap alternatives to creating short animation videos? Even if it's combination of creating my own through iMovie/quicktime/etc... open to all suggestions!

Thanks
