If you're on OS X and like Vera, you might take a look a Panic Sans, included in the app bundle of Coda. It's a tweaked version Vera Sans Mono. I can't put my finger on what they tweaked, but it's been my preference for some time now.

I like your syntax coloring, what editor/color scheme?

Most likely Textmate with the railscasts theme (http://railscasts.com/about).
