ok, well here are my thoughts! When i was looking for a puppy i was a nervous wreck about being lied to or cheated or even picking a puppy and it changes in the time being and i get given a different puppy. I chose mine when she was 4 weeks old! and yes, often some of these breeders are just in it for the money, and then you get people like those i have met on this site who dote on their pets and it is a priveledge for them to breed bcos they put so much love and passion into their dogs.
I was not looking for a dog that I would show, so for me the fact that she is registered and her parents were of good stock was enough for me.
I think it's important to let us know WHY you want the dog. Is it just for a companion, or are you wanting to breed or show with her. If it's for a companion then you want to make sure her personality is sweet tempered...actually either way i think her personality is very important! I recommend a thorough vet check for her health, and maybe try and spend a day with her in your home and see what she's like personality wise.
But I think she's got a cute little face

But I'm a softy for all living and breathing things, especially my Yorkies. If I could have a whole team of them I would do it RIGHT NOW!
good luck - sometimes price isn't everything. Take your time in getting to know the dog. and even tho people who brought her up bcos the owners character plays a big role in any dog's temperament in my opinion.
