Well of coarse I'm going to say buy eggs from those of us here on BYC...many of us have the breeds you listed Your not going to get quality birds hatching eggs from McMurray or any other hatchery if your looking for birds that meet the breed standard or supposed breed standard-Blue Lace are not an accepted color yet but we love ours anyway
Egg prices really depend on the quality of the parent stock..better you buy the more it will cost in cash but less time to a higher quality flock.
For instance on your list we have Black and Blue Barred Plymouth Rocks and BLRW-Foley bred so chances of hatching single combs are less than other breeders he's breeding that out of his line.We have several breeds you didn't list that are great layers and great birds to be around the list is long
