I'll suggest you look in the archives of

the July 2003 issue. Both magazines have a description of what sergers are, which might be best for you, etc plus a list of manufacturers, models, their stitches, tensions,and other comments. Also online at the different machine websites are more descriptions w/illustrations and sometimes MSRP. Remember though, sergers and sewing machines are like cars, different brands fit different people. You can do lots of research, then give your wife a card w/a note, such as gift-one serger, then take her to the store with scraps of fabric she will be more likely to sew and she can then make the decision on which one she prefers. You do need to look for a good dealer who will allow her to try out different ones and will give your wife service. Personally, I am totally sold on the Pfaff machines & sergers, but some of my relatives & friends would never use a Pfaff. As with all brands, there are different models, I have one serger that is about 10 years old, and
3 years ago, I upgraded to one w/cover stitch and all the bells/whistles I think I will ever need. I am a Gramma, too and most of my sewing is for a young grand daughter. Wish you great success. Emily
