I do like Ameraucanas, but it's so difficult to find good breeders who know the difference!
I might start with Orpingtons and then add in some Ameraucanas later.
You can check the breed clubs for breeders...Orpingtons or Ameraucanas. That's what I did, and I got some hatching eggs. Also, look at poultry shows and meet people. They tell you about other people that are breeding good birds. Generally, I found the folks to be helpful and friendly.
