Hi Enderwiggen,
I bought my Brother sewing machine off of Craigslist for $75. Is it top notch? No. Does it have all the bells and whistles? No. But it's mine and I love it. I would love to have a high end embroidery machine, but that probably won't happen in this lifetime.
I would suggest going on Craigslist. I know that I am always seeing "brand new in box" listed for little money.
Another suggestion - if she watches ads and looks for coupons, she can get quilting supplies and fabric for much less.
That's what I do. I could never afford this hobby at full price.
