One thing I would consider before making an investment in a new machine is the location of the dealer, the expertise of the staff, and the availability of service and repair. My dealer is close by, and it is nice to be able drop the machine off when I need to get it checked. They have a certified technician on site. The dealer also offered hands-on classes to help get the most from my machine. There are a lot of good sewing machines out there. Have fun finding your favorite! Take lots of test drives.
BTW: I have a Bernina 1530 that I have had for over 16 years. I still love the machine and have not been tempted to trade it in on a newer model. (The prices have gone up a bit since I bought mine.)
