It's a great machine. You might want to run a "completed listings" search on eBay to see what that model has sold for there in the recent past (EvelynAnita's purchase is probably in there). You could maybe bargain the price down with printouts of eBay sales of the same model. $1800 may be what local dealerships charge for this machine, but that's an entirely different market. You might want to call around to dealerships in your area to see if they have a used version of this model and what they would ask for it, just for comparison purposes.
Be *very* careful about shipping, though. Most people do not know how to package a sewing machine properly so it is not damaged in shipment, including a lot of packaging stores. For example, the case/cover needs to be packed separately, and it's a good idea for the machine itself to be double packed (a box inside a padded box). If you pay for insurance and there is damage, it's up to you to collect from the carrier, which can be a hassle.
