If you try and use only "free" stuff, you'll find you get lot of other stuff (advertisements) that clutter things up.
The best is rarely free, but it doesn't have to break you. Go to
www.apotheosispictures.com. They will set you up with a superior formatting program, SCREENFORGE, and let you use it FREE until you decide whether or not it's what you need. Then, it's only forty-five bucks, which is extremely reasonable, and you get no annoying pop-up ads or other distractions. It's certainly been worth it to me. You can even use it for shooting scripts, it's complete.
Tell 'em I sent you!
