Stated quite well, and I agree, Ninja! For buyers, you should do your research and KNOW what you are getting. Reputable sellers will provide pictures, pictures, and more pictures of their stock and eggs, and good ones will even send eggshell samples for you to see first-hand.
Another issue is that there is a limited gene pool of good Marans here in the U.S. IMO, there are lines where the birds are absolutely GORGEOUS, and to the standard being proposed to the APA; however, because of line breeding, fertility and hatchability have been compromised (again, just my opinion in what I have experienced). It's a catch:22. Line breed for best traits and to eliminate worst ones...but after so long, fertility goes down. But, outcross and you take the risk of egg color getting light. You have to be so careful crossing lines...again, research is essential!
