Patti, do you want a new machine for the decorative stitches? It is important to figure out what type of sewing you do. When my Viking died and couldn't be repaired I was in a hurry so I bought what I thought was what I needed (I didn't think it through). There is nothing wrong w/the machine I bought but I've recently been buying a few vintage machines (some from the era of your Kenmore). They have stronger motors and I just love the power they have. You can get several different aftermarket feet and attachments for most vintage machines. I've also had some luck on e-bay.
There is also a "Vintage Sewing Machine Shop" on this board and the members are very helpful. Some of them may have what you need or be able to direct you to where to find it.
Regardless of what you do I hope you find the perfect sewing machine for your needs.
