At the same time, decide which you want to buy before looking out for the price. I would advise you to decide the type of camera you want before considering the price. These 2 are very different type of camera.
Bro, Song bros has pretty bad reputation in the past. Maybe it's all in the past now, any recent trips that I tried testing water at Song Brothers, I got quoted price way higher than street price. If you want great service and willing to spend a little more money to enjoy it, go to John 3:16 on level 5 Funan center. If you are buying, you'll be served like a king, even if not, they treat you like gentlemen in a classy restaurant.
If I was to buy a D7000, I would not buy the kit. I would buy a Tamron 28-75F2.8 to go with it.
I once bought a samsung P&S camera from a retailer on the ground floor of Sim Lim Square, and the photocount on the little camera out of the box was 5K+. In my mind, I got a used camera. So you see, I am very wary of Sim Lim Square. Now I just go to Gope's or Cathay photo.
