People going on about "market price" usually have no clue about economics.
The market price is the price the market will bear.
Sooner or later you will see Bamboo, Ghi and Coral Glow going for $200 a pop. Expect it.
Quality animals with patience can always command a higher price but, if you think you are going to get rich selling snakes from a $5K snake breeder indefinitely, you have another thing coming. Every single snake you produce(and you must remember you aren't the only one producing them) drives the price lower and lower.
Keeping these morphs out of the hands of everyone that desires them is hardly the answer. A few will make a buck by getting in early or focusing on specific projects of high quality animals. Getting in early involves risk, which is why when it does pay off (and it does not always do so), it tends to pay a larger dividend.
The market for 4 foot snakes is not dead due to the second incident involving a rather large snake in Canada in 2 or more decades. The market is going soft for crap quality animals, since anyone can easily breed these animals, where as higher quality animals although not worth their weight in gold can at least keep you in feeders for your hobby and if you apply yourself with a little luck and a lot of passion you just might do way more than subsidize your hobby.
