I have a Baby Lock Imagine and I love it for the finished edging it gives. Am currently making a quilt-as-you-sew throw on it for myself. They're rather fun to make - this is my third one.
And for clothing, it does make a nice finish inside whatever you're sewing - raw edges don't look as nice. Made some things for my two and half year old grandson and the insides of the shortalls and overalls do look more professional.
