I have a Sartek GoPro Hero 2 housing excess to my needs. This is a flat mineral glass lens housing only and renders excellent video underwater. If you shoot 1080P with this housing, limiting the FOV to Medium eliminates any vignetting. Housing will arrive with the OEM back which would not accomodate the auxillary battery pack or the LED screen. It is used, but in good condition. No leaks. One thing with this housing, you HAVE to turn the camera on BEFORE you get into the water. Attempting to turn the camera on upon reaching any sort of depth apparently will result in a button jam which freaks the Hero out. If the camera is one before you get into the water, you can start and stop video or pictures with no problem. $25 shipped to you. I can include mounting hardware for another $5.
