Late last year I transitioned from Livebooks to Photoshelter. Overall, I'm very happy with their service. My website utilizes one of their Beam templates. The site builder is easy to use but quite powerful, allowing you to somewhat customize your website. e-Commerce is built in and works well. The SEO seems to be pretty good, too. I'm already seeing about 30% more traffic than I was with Livebooks. I wouldn't hesitate to recommend Photoshelter.
