I got my youngest, Bristol from Betty Fitzgerald in Prosper (north of Frisco). Here is a site with her email and phone number.

I shopped around and she had the best price and let you go out and see all the pups. Bristol is a 3 lb and I got him for $750 (when most sold that size for around $1,500 - $3,000).
Hope this helps!
