I have a hero 3 with the different housings and charge cable for sale $100. The front display is messed up but I have the lcd display for the back of it and it is a touch screen so you dont need the front display. Pm with any questions.
Yes it is still sealed up and works fine. The lcd readout on the front screen is half black and not readable where I messed it up putting it back in the case I can text a picture if your interested.
