Good great dane breeder in/around Houston, TX...price is not an issue?

I'm looking to buy a black male great dane, and I want a purebred and one that comes from a healthy line, no bad breeding, no hereditary diseases, etc.etc.etc. basically i want to find a quality breeder in or around Houston OR I would be willing to import it, so to speak, from somewhere. Willing to spend up to $1500 on puppy and getting said puppy here from elsewhere(if necessary).
