I paid about $3000 for my B 440 QE without the embroidery about a year ago? I just picked up a new quilting book that has the B 550 QE listed at $4,399. I would think that you wouldn't have any trouble selling it if you have a quilt guild in your area to advertise it. Maybe even someone close from the QB would be interested in picking it up. As for price....$2000 maybe? I don't know how much you paid for it originally and if you can't recoup most of the price I would just keep it myself.
