Screenplay Writing Software

What software for script writing is the best out there?

1. Visual Studio is always the easiest to use but expensive. I use TextPad when I am paying.
2. Final Draft 7. I think it's simply the best program. Easy to use and get into, automatically formats your writing and even comes with several different set ups (i,e script styles preferred for BBC, half-hour sitocoms, Warner Brothers projects, stage plays, etc).
