As if I needed another reason to love Sublime 2, I discovered I can import and use Textmate themes.
Go to Preferences -> Browse Packages and put the tmTheme file in the User directory.
Restart Sublime 2
Then, go to Preferences -> Color Scheme and it should be in there.
My favorite scheme is the theme created by Ryan Bates of railscasts.com. You can find the theme on the 'about' page of railscasts.com
