The ones you listed are reputable as far as I've heard. I don't have any direct experience with breeders though. You may want to visit a reptile convention so you can meet with some breeders and take a look at what they have to offer.
theres alot of good breeders in the usa that ive heard of you got so many to choose from here in canada were very limited but a few off the top of my head are

I got a juvenile dragon from David at Carolina Classic Dragons (http://www.carolinaclassicdragons.com) two weeks ago. He is incredibly tame, friendly, great eater, and beautiful coloring. Highly recommended--David has a bachelors degree in biological sciences, reads university papers on the care of bearded dragons, and passes his knowledge on to his customers. He answers all my many questions about my little guy. If you check out the Carolina Classic Dragons Facebook page, he posts specials and sales quite often.
Currently trying not to stress over my anemic dragon....she is being treated, but I don't agree with her treatment plan and have been seeking out a second opinion from another vet. If anyone else has dealt with anemia, please let me know how it was resolved. I am losing sleep over this
Another post lol. My beardie does not like enclosures. Her tank is the kids room and she has created a nesting/bed spot in the corner. She will cuddle with my son but she know when the lights are out and the kids go to sleep, she literally goes to her bed like she is our 3rd baby. I love her. And to think, I never wanted a beardie lol
Please help. My beardie is my baby and I am worried she may be egg bound but I can't tell. She is over 2 yrs old and has never laid an egg. She has been swollen for two days and can't tell if she may be impacted or egg bound. Please help.
