Hello,
I have been a member of Imagekind for over a year, and although I haven't bought any of my own stuff, I have heard very good things as to quality from those who have. They take care of manufacturing, shipping, customer service etc. All the artist has to do is upload images. They have free memberships, and paid memberships that offer unlimited amounts of space and a "storefront". I haven't sold anything except a couple of greeting cards, but as a gallery site, which people CAN order from if ever anybody wants one of my images (it could happen some day! at least in theory!), it is pretty good. It's also got a lively community and forums.
Here's the link to my profile page:
