I agree with Dolphyngyrl that Brother machines don't seem to be picky. My Brother will use any thread without a problem, cotton, poly, doesn't matter. I have switched to using topstitch needles only because I like them -- they give the thread a little extra "eye" space and I also find them a bit easier to thread (could be my imagination!). I wouldn't worry too much about what brand of thread -- my Brother likes everything and I doubt you'll have issues with any decent quality thread.
