I have a Bernina 630 which is the same thing, basically, just a couple years newer. I love my machine. It has lots of stitches and one of my favorites is a "meandering" stitch. Does it come with the Embroidery Unit? Part of the upgrade on my machine is the Bernina Stitch Regulator foot, which is great, though not a necessary item.
I don't know about the price, I paid $2700 for mine, used, about 2 years ago on e-bay. You might check e-bay and see what they are listing/selling them for on there.
