Many years ago, I picked out a specific sewing machine that my husband was going to buy for me. The reason for this particular machine was it had many quilter friendly options that my simple present at that time machine didn't. I explained this to him and he still bought something else because it was a better price on e-Bay. It was very difficult to even fake being appreciative. Didn't want to hurt his feelings but I hated this machine. He still says that what he chose was the exact same thing. It was nothing but trouble for more than a decade. Best to let her pick out exactly what she thinks she wants. Maybe after trying out other machines, she might even decide on something else. It is a very personal decision.
