The price of crested geckos is not in which "morph" it is.. the hard work goes into selective breeding. Breeding for a specific color, or pattern etc.

I'm not 100% sure if anyone knows whether or not the harley/flame/pinstripe patterns are all controlled by a single gene, so those might be considered morphs.. Same with dalmation spots?

Anyhoo, you can get very nice looking crested gecko hatchlings at under $100.

You can get incredible hatchlings under $200.

I've seen some ridiculously cool looking geckos at $300+

P.S. you will want a bigger tank than a 10G for an adult.. it's a good size for a juvie gecko, but I keep my bigger adult male in an 18'' cube cage.
