Cattitude ... If I were getting a 2nd machine, I would factor in the similarity of the machines. Would I enjoy sewing on the 2nd as much as the 1st? That would be very important to me, otherwise I would start to hate the one machine and next thing, would not want to use it. Could the feet/accessories from one be used on the other to save the need of buying more feet? Same breed of machine does not mean the accessories are interchangeable.
Not sure which dealers you are including as your close by options, but if not, add in Triangle in Guelph as one to check. They do take trades, and offer them for sale. Sometimes with very good pricing ... and including a warranty
with the used machine.
Good Luck in your quest!
