Anyone else use FiveSprockets? Ideas for other free alternatives?

I used it for my first full length and was pretty impressed. But it was difficult to transfer the formatting over to a word doc. I also have a feeling the formatting is not quite up to regulation.

Thoughts? Ideas for other free alternatives?

I use Celtx.

I don't know how it compares to FiveSprockets, but I'm pretty happy with it.
