I bought a male dragon from Carolina Classic Dragons back in April after having lots of problems with our PetSmart baby that ended up not making it - sadly.
They were very willing to answer any questions I had since I was fairly paranoid after a bad experience, and the dragon was packeged well and shipped overnight. When I first opened the box, it was alert and active. I placed him in a box with a heat source since I was at work and within minutes he was eating his tiny crickets and greens. CCD only shipped M-Thursday incase of rare delivery problems - so that if there is a problem, it won't end up going over the weekend.
He has grown from 8" in April to 12" now in 6 weeks and is active and eating like a beast - both greens and insects. Such a huge difference from the baby I got at PetSmart. I do have to say though, that via e-mail, they can be taken as being curt. But they aren't - rather just answering your question and moving on the next of a hundred e-mails without a lot of chit-chat. I found that when I called, he was pleasant to speak with. The do list a lot of dragons on Facebook as auctions and sales. So if you are interested, check out their Facebook page as there are often dragons there that are not listed on their web site. They also post updates as to any clutches/hatches etc. that are happening with pics of the babies as they hatch.
They do feed their dragons with pellets, which I don't really see a problem with as it's not the ONLY source of food. It's part of a varied diet. Variety is the key to health with any animal/pet. I have also heard great things about Rio-Reptiles, but they only had leatherbacks, whcich we did not want. I had read mixed reviews about Fire and Ice, and I also looked and several others, though not sure off had who they were now. You can search the boards here, and check fauna to see reviews and make your own decision based on what you've read.
I think having them shipped is fairly safe as long as you buy from somone with a good reputation. As an earlier poster said, and as CCD had said to me, they aren't willing to risk their hard earned good reputation by selling sick dragons.
So, long story short, I was pleased with my purchase even though I didn't get to see the little guy in person first.
