I have bought Bushnell, Browning and Wildgame cameras from ebay over the years.
The Bushnell and Browning cameras have been pretty dam good and going strong.
It is very bloody slack to lose a camera due to thieving. I haven't had that problem possibly because my cameras are in areas with fewer hunter numbers.
