As everyone has said here, don't get into it for the money! Yeah Justin and I make money from the snakes now but 5 years ago and no one would have know who we are, we breed what we like and we look at what other people like. Don't buy a spider and think you'll make bank it wont happen. We have a harder time selling normals then anything else. Everything else flies out the door! Just know what animals people like and what you like. From the sounds of it you jut need to be able to sell of what you don't want to keep, so breed high quality examples of the morph you like, thats where the key is. Have good examples, be curtious to everyone and keep them healthy!
Like I said our morphs fly out the door, we only have 11, 2010 Morph Ball Pythons for sale right now out of 250+ hatchlings we produced this season!

Have fun with it, if you can afford to get nice stuff you like get it, the fun part is trading with those nicer animals not making money!
