Here is a link to a lot of good information on them:

If you want one, you generally need to put a minimal deposit down and get on a waiting list until the next litter comes in with whichever breeder you want to deal with. There are many on the internet, easily accessible on Google.
They are a bit pricey, but not too bad. You can expect to pay anywhere from about $500 up to and over $2000 depending on the location, breeder, age, and many other factors.
