I've been searching for used D3s locally for sometimes but no luck after 6 months. Yesterday, my favorite used camera shop told me they have used D3 in stock for $2700. Since my target is always focus on D3s, D3 is never on my list. I only know 720p video feature is not on D3. If video feature is not significant in my lowlight indoor event, soccer, landscape, wildlife photo shooting, shall I take this used D3 rather than waiting forever for D3s ? What are the differnce between D3 and D3s ? Thanks.
