I wouldn't spend that much money on something that isn't as it should be. I would go so far as to say that if Xootr is aware of the problem, they should either not be selling them or making sure people are aware of it before taking their order (and offering a discount.) I know I'd be mighty irritated that if I tried to fit big apples on my Xootr 3 years down the road and they wouldn't fit because of manufacturing defect.
Any reason you are opposed to buying a used one?
