I have heard more horror stories than good ones from ebay eggs as well as oakridge auction eggs. I myself would try and find a breeder of a strain before worrying about someone having the right name on some eggs to get them sold. Now I do know of some very fine breeders that sell eggs and fowl on those formats, but they are the exception and not the norm. As for the birds you are interested in, Cuda was selling pumpkins recently, the other strains are a bit harder to find, but a google search will get you some breeders sites.
