I would not deal with this individual at all. It sounds like she is only interested in how much she can get you to spend and not at all what you are telling her you need. I won't deal with any sales person who doesn't listen to what my needs are and try to help me find it without trying to upsell me.
Go to a variety of sewing machine shops and tell them what you are looking for, then try them out. You may also want to ask what they have used. There are many really good machines out there and yes you can get them for $1000 and less. It is a matter of finding which ones fit your needs and what you are comfortable with. They are like individuals, they have their own characteristics so some match your needs better than others. Good luck finding that perfect one for you!
