Does auto-complete for Unity(java)script with any free text editor?

I am currently using TextWrangler (despite it's goofy icon) but would be happy to switch to any free (or really cheap) Mac based editor that supported Unity(Java)script autocomplete.

If you have the steps to get "Wrangler" working, extra props!

There is an excellent overview of Unity script editors up on the Unify wiki that covers the available options for each of the Unity scripting languages.

The editors with autocomplete for Javascript appear to be, TextMate for Mac OS X, or UnityDevelop for Windows.
