You should be able to get a nice Desert male for $1500-$2000 so it will definitely save you some money going that route and making your own. Hopefully you already have, but I just wanted to make sure you have researched the Desert and the fertility issues the females have. It won't be a problem for you since you are getting a male but could possibly casue problems when it comes time to sell your babies.
I'm not trying to turn you off of them just want to make sure you have all the info before you decide to get involved with them.
