I'm in need of an application that can do something like Marked for OS X does.

The function I need is a bit more specific: I want the app to export Markdown to PDF, but using CSS - I've achieved this using BBEdit (using <link rel="stylesheet" href="file.css" /> and exporting, and with Marked, I can just select the CSS file.

I'm using ReText for Markdown editing, but said method doesn't work - the PDF exportation is posible, but without styling.

Any way to achieve this? I don't mind using the Terminal or any library lying around - if I can achieve the desired results.
