Good luck on testing out the machine. You sound like me...I stress over these kinds of decisions. I really do like the yellow cabinet although it wouldn't match anything in my home either. However, I would NOT hesitate to offer them less...they can only say No and then you can decide if you want to pay the full price. AND you will love having a 15-91. I was given one but not in a case or cabinet and I enjoy sewing on it. It zooms, too!
