This is an amazing machine. If you have the ability to get it, I would absolutely dive head first! I LOVE mine, and it does everything I ask of it. The piecing is so accurate, the FMQ beautiful, and the machine is a workhorse- it sews full speed over jeans hems without hesitation.
I got mine this summer and paid around $2,200, with a trade in. It also came with the embroidery module as an incentive (normally that would be another $800 or so).
$2,000 sounds high, because I presume that means there is no warranty. Have it checked by a Bernina mechanic- is everything in good working order. Does it come with a number of feet (they are expensive, that could be a good value.)
