Given they were both in the same condition. I shoot NCAA basketball and lug my camera around a lot. I like the build quality of the D200, as well as the button layout for changing settings. I know that I will be downgrading the sensor and Mega pixel's from m D500, but the build, customization, and slightly faster burst rate makes the d200 an appealing body. Any insight on this trade? Good idea, bad idea, fair?
