hi,
i don't know about a brother machine, i have a bernina. but i would suggest buying a machine where you can go and get help or classes with. even shops that are dedicated to sewing machines, have some that are not to spendy and they will be there if you have questions or problems with the machine. most of the big box stores do not offer any sort of back up if you have problems, you are pretty much on your own.
if i was buying new, i would buy something from a local shop, given the choice...just a thought.
