Consider getting an Azor Front Rack for that bike, it would look great. I have one and I really like it because it's a front rack that attaches to the frame, not the handlebars.

I have a porteur-style bike with a velo-orange porteur rack and, frankly, it's a pain in the neck because it affects the steering when you have a heavy load on it. In contrast, the Azor rack doesn't move with the handlebars and is thus much more stable, especially when I have my computer, a bottle of wine, and two bags of groceries stashed in it.
