Hey! Adding to the threads about cover services, here's one I used for Tainted. I bought the $50 as-is image and tweaked it myself in photoshop, but you can also pay extra for customization. As far as professionally designed covers go, $50 is pretty damn cheap. Plus, once you buy one, it's taken off the site—no multiple covers running around out there.
