Lab breeder help

So I plan on getting a lab puppy soon and was hoping some people who are more well-versed in distinguishing great breeders from not so great breeders could help me out. I know many will probably be against the idea of a puppy, but with young children and another on the way I just don't feel comfortable bringing in a rescue. Anyways, I am currently looking at Misty Woods and Blackberry Hill labradors. Does anyone have any good rescourses that help me very reputable breeders. I have done some reading on it and a lot of what I've seen is very vague. Also, any opinions on these 2 breeders are more than welcome. Thanks in advance for any input.
