Have been watching the marketplace for a while and there seems like most of the gear for sell is Nikon. Not wanting to start a Canon vs. Nikon battle, but it seems like it has to be one of these: 1. This forum tends to cater to Nikon users. 2. No one sells Canon once they own it. 3. There is just a lot more Nikon gear out there. Really just curious as to why the marketplace is so heavily weighted with Nikon.
