I purchased a pair of 4 gram hatchling crested geckos from Matthew Parks of Pangea Reptile back in November of '09 and since then they have grown up to be perfect examples of what a Crested Gecko should look like. Even better, they
both turned out to be females, which in the crested gecko world is an A++. Matthew's customer service surpasses that of any other crested gecko breeder out there, he is quick to reply to any emails and or questions you have and properly packages ships his geckos with care.
Best thing of of all, Matt's geckos are top shelf, here are pictures of the two he produced that I purchased from him, they exhibit excellent crest structure and form. Highly recommended breeder.
