You must be a very special sister for your brother to purchase a machine for you. To me either one would be great, however the black one appears to have more attachments that the white one. The other thing to consider is, will this be your MAIN machine or a class one. Will you sew only straight stitches or sew everything you can? How often do you plan on useing it?
Best of luck with your choice.
