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.
I have questions about bubbles on our bearded dragons eye.
So he’s gotten bubbles on his eye. We wiped them off and it’s only been twice in the last few weeks. Should we be concerned? No coughing or congestion. He’s very hungry and sleeps well. He’s 8-9 month range. His humidity is 30-40 day time and as high as 50-55 at night to early morning.
Should we be concerned?
