This woman sounds more like a hobby breeder than a puppymill. She probably has a couple liters a year of pups and knows enough about breeding. I'd ask for a health guarantee. The fact that the pup has no papers means little if you are just looking for a pet to love. I wouldn't breed your baby.
How many dogs were at her house? Did you go to her house? Was it clean? $400-$600 is a good price for a pup with no papers, putting the dog on 'sale' is a red flag for me, but she might have her reasons. I tend to be a bit naive though and trust others right off the bat. If you get a health guarantee, saw the parents and are happy with the pup and feel it is a good fit, then go for it.
(don't bash me for saying this)
