I am currently looking around for a fast lens to replace my kit lens.

There are 2 choices here since Nikkor is just way too costly for me and will totally blow away mine budget away. So it will be either Tamron or Sigma.

Tamron SP AF 17-50mm f/2.8 XR DI-II VC (Vibration Compensation) here & old one here. The new series comes with VC for nikon and seems to be one of cheapest around at this build quality. Overall, Tamron received a better review compare to Sigm 18-50 for its superior sharpness even at wide open. The only know issue with Tamron is the “back/front focus problem” many had talked about.

Both lens are around selling price of RM2K.
