Grandma Jeanne, I have 2 embroidery machines, both Brothers. One is a combo machine with 4x4 stitch area and the other is embroidery only with 5x7 stitch area. I, too, recommend going ahead and getting one with a 5x7 stitch area. Brother and Babylock are good machines. I bought both of mine from a dealer and they were refurbished machines...like new with new warranty. Have had NO problems with them (except user error LOL).
Also, there are a couple of Brother 770s listed over on SewItsForSale site. Very reasonable!!
