I bought a Nikon D3300 from camera zone at Majestic City a few months back. Like you, I researched a lot of places before buying a DSLR.
As per my research, cameralk's items are of good quality but their prices are high compared to others. If you are hoping buying a Nikon DSLR, you can get a good deal from its local agent (Photo Technica) but check whether they have stocks (Photo Technica did not have D3300 stocks at the time of buying my DSLR).
Prices of clan is cheaper but I don't know about its after sales service. If you have someone in USA, try to import a DSLR from there as it is about 35%-50% cheap. Or try out from following places,
1. Photo technica (Nikon only)
2. Cameralk
3. Clan
4. Camoron trade connections
5. Camera Zone
All the best
