Dachiu has some of the cheaper prices out there.
You might also check out bloodbank. They run specials from time to time but even then it's still going to run you 150-200.
The reason for that price is that most breeders don't sell until a certain age/length combo, usually 6 weeks and 6 inches. So when you buy a dragon it isn't just the morph you pay for. It's them recouping some expenses for the food, electricity, supplements, etc... Then shipping can run anywhere from 35-50 bucks depending on how they ship so 150-200 shipped is really a good price when you consider all that goes into getting them to a healthy size and age. If that price is just too much then consider checking craigslist and rescuing one.
I know it sounds like it but I'm not trying to lecture you, just explaining why they cost that much from a breeder lol Sometimes people don't realize how much work goes into these little guys. When I was breeding I easily went through 2-4000 crickets per baby before they reached the appropriate age/size. Some were more, some were less. That's an average of 30-50 crix a day per baby, which a healthy beardie can easily put away. At 4.5 months Harley knocks down a salad and 20-30 dubia, 10-15 crix and a couple of either horns or waxworms each day.
I've bought from Dachiu twice and both dragons are amazing. One of them was years ago when I bred myself and he's since been sold but my new girl Harley is from them and she's gorgeous and super healthy. She's about 4.5 months or so now,super chubby and over 14 inches. She eats like a pig and has a fantastic temperament because Dachiu handles all their babies to get them ready for new owners.
