I love Ebay...even bought a used Toyota Corolla Wagon for work from a dealer in Ohio (about 6-8 hours from my home). Anyway, back on track. I am sooo glad you decided to go with the Bernina from a dealer. I don't know about your dealer, but mine has a great rep and gives great tradeins. I got a used 440QE, with very few hours on it for about 1/2 the price of a new one with all the attachments. free lessons and the remainder of the 25 year warranty. I am in love!! Went back and got a good deal on the embroidery module 3 weeks later.
When buying on Ebay, I do as the others suggested - research the product and the buyer thoroughly.
Good luck with your new machine! Enjoy!
