We have an NXT kit, and our brain's screen has died, which makes the whole thing pretty much worthless. I will pay a fair price for another one! So, if your child has decided they don't want their NXT set any more, or perhaps your child is so gung-ho that you have upgraded to the EV3 and no longer use the NXT brick, I would love to buy it off of you! If you are interested in selling other parts from the kit, I may well also take them off of your hands, but please do understand that I am really most interested in the brain/brick part. Thanks! --Emily from King Ave *Want better, safer products for your home?* *Want them at better-than-grocery-store prices?* *A few minutes can have you all set up with your own portal to environmental friendliness!*
