Cases for Macbook Pro 13"

I am going to buy a new Macbook Pro 13" soon and have been looking at what case would be best to get. I am interested in getting a foofbag . My only concern is that when it's not in the bag it's vulnerable to scratches, grease and dust. A friend has a Speck shell-case thing (I think). When looking for one I found articles that the Speck cases scratch the macbook and cause more damage than protection. Im very OC about my electronics . If I was to get a hardshell case, any suggestions?

Thanks,
