I love my Pfaff's! I agree you'll get a lot of opinions.
I'm a tad confused. Is there another reason for getting another machine? If your present machine sews well, it should be able to quilt well. Granted you may want a walking foot or such. Your feed dogs must drop that if you do embroidery on your present machine. You can always just buy, or have made for your machine, an extention table.
That way you could spend your savings on a special quilt show or camp or something.
