My 7 year old granddaughter made her first quilt on a $10.00 mini machine I bought at Rite Aid. It runs on batteries or electricity and we took it camping. It is just like this one

I later got her a Janome sew mini Paid around $50.00 for it

If I had it to do over I would have spent the money on an inexpensive full size machine from Walmart. If she continues to be interested she can always upgrade to what she wants.
