I would try out any that I could but also consider the service and reception of the store selling the item. Do you sincerely feel you will get extra assistance if you have trouble with the machine or just don't understand how to do something. Will they do it free or charge you for their time each time you ask to be shown something? I live in a relatively small area and so bought a Husky serger 60 miles a way. They will give free lessons but I hate the drive. I bought a Baby Lock quilter and love it. It was a demo used in classes at a quilt expo so got it half price. E Burns had taught and there were several new machines for the class to use and then sold 1/2 off with financing free for 12 months. I really like it. Love the 3 stich in place start up, push a button at end of seam and it locks the stitch ( 3 stitches in place), thread cut off button, presser foot lift button. Lots of auxillary stitches and lettering. Good Luck. Let us know what you get.
