Can't help with the Iron Mike lines but
www.flyingoranch.com is where all our Britts are from. Ed has some great pups.
A word of warning regarding Flying "O" Ranch: I did business with them last year - I even had a deposit down on a puppy after seeing recommendations from this forum. After I asked Ed multiple times about their puppies veterinarian care (my wife is a vet herself, so this is important to us), I received the response: "I have been raising Bird dogs and training for over 60 years. I don't need A vet to tell me about my dogs. you can have him checked out and if he finds A problem I will gladly refund %100 of your money."
I'm sure he has some great pointers, but this is not someone that I wanted to do business with. After I ate my deposit, the breeder that I wound up using also had some negative feedback on Flying "O" as well.
