Check out the SJ4000 clones on EBay $20-$40 each and not bad at all. My friend bought one to try it and then converted it to Full Spectrum for shooting in Pitch Darkness with an Infrared light for Paranormal Investigations. Is posting links to videos allowed here? If it is I'll send the link to his videos on Full Spectrum. He then did it to his GoPro Hero 4 Black. We used it recently on a Paranormal Investigation at a Revolutionary War Battle site.
