i have a friedn that does a LOT of sewing and stuff - she will ONLY buy brother - and only the ones that number ends with D (there is something about them but not sure what)

she woudl never buy a two in one (and has forbidden me to do so) - they have very different functions and should be kept seperate

having said that, she does a lot of embroidery - if you're looking to just do very basic stuff, it might be ok...
