Summary: Be honest. Buying a 3D video cam for less than $100.00 you shouldn't expect much. This is a great cam to keep around and take home pictures or throw in the car "just in case." I've taken a few videos and been satisfied with the image and sound quality for the price. The operation, playback, and transfer of images to computer and TV are very simple. If I were going to a major event, I would not use this camera, but it's great for just day to day things.
Summary: Dont buy a used one unless it is dirt chesp as you can get them from aiptek direct pretty cheap these have a better stereo base than many 3d cameras but less than the fuji but they come with good free software and they are cheap
