I have the Brother SE270D which has a 4x4 embroidery area. I also have a Brother PE700II which has a 5x7 embroidery area. If you can, at least get a 5x7 area although I do like my 270D since it is a combo sewing and embroidery machine. I bought both of mine refurbished and they have been great...save a little money that way.
Good luck in your hunt!
