Used D3 for ~3000? or New D700, MBD10 grip, ENEL4 battery, MH22 charger, and BL3 battery door for ~3000? Im never gonna shoot professionally anymore and one thing I love about the D3 is/was its battery life. I suppose Id get that with the D700 in this configuration... Id lose a card slot and some weather sealing but I dont know that I care about that anymore. Thoughts?
