She's wrong if she thinks you can't find one that size for less. I know of two that are 1 1/2 pounds and 5-6 months old. One is $5000 FIRM and the other is $2200(they say past puppies have only matured to 2.25 pounds and the parents are not tinies but I did see a picture of the puppy, she's a cutie). I'm saving their number in case I ever need another one.
Here's the first one:

I'm not going to post the number for the second one because I'm still so undecided.
