The poor little guy. Maybe $600 doesn't sound like a lot for a pet quality "maybe Yorkie", but if this lady wasn't a consciensous (sp?) breeder, does she watch her line for luxating patella, liver shunt, or any other costly defects? Luxating patella's can run into thousands of dollars in surgeries. Ask me I know! In the long run it's not such a bargain. As for me? I would pass. You can find other yorkies for a reasonable price that look more like Yorkies. JMO
