Amazon was selling the 3401 for $350, and I can get free 2 day shipping so I decided to buy it. They stated new condition and it was sold through Amazon, not some shady seller. When I got it, I noticed the box was damaged (not the shipping box, the actual box the machine comes in). The flex seems to be working good, and I can't tell that it's damaged in anyway, but for some reason I'm a little paranoid about it. The total was $372 because Amazon charges tax (so not as great of a price but still discounted) Should I return (free return shipping) and buy one elsewhere or do you think it's fine?
