Good Free Rails IDE for OS X

I have tried Eclipse, Aptana, Redcar, Textedit, Komodo Edit, Titanium, Netbeans, and Vim. Is there anything you can thin开发者_开发百科k of that i'm missing? None of these really satisfy me.

I think the question here is what are you looking on an IDE? what must they have for you to like it? In particular, I use Vim with this https://github.com/joseicosta/janus-tweaks. This provides me all I want, and with the lightness inherent to vim.

TextMate is a popular "IDE" that runs on OS X only. It costs $$, but well worth it.
