I'm wanting to quilt my own pieced quilt tops so want and/or need only a straight stitch machine. I have a Janome with lots of stitch patterns I seldom ever use. Should I buy a 5-year old Babylock Quilter's Choice Professional for $450 or a used in good condition Brother PQ 1500S for $500? Like what I read about each of them but am leaning toward one of those choices...... so bless your hearts, I'm passing the buck to ya'll.
