I've got or had a 07, 11,14 and 20. No problems with the 20 and it seems perfectly fine. I do like the style of the 14's better and it has been an excellent machine. I'd still prefer to buy the new one, but I would not shy away from an extremely low mileage 12-15 in excellent shape. I wish I would have bought another 14 at the time as it was pretty affordable and a damn good machine.
