What are you wanting to do with your machine?
I am upgrading to a big girl sewing machine because I want to sew all stuff not just quilts. I am getting a Juki tailoring machine for 1400. - it will sew!
For playing I love my Bernina's
One I use for needle felting more then anything else - it was the cheapest and I have the least problems with it.
I like my anniversary 9mm more or less for free motion embroidery.
My other one is in the shop for an annual - I like it 2nd best - I think it is a 160.
