D5100 or D3200??..pls help

Hi Guys..i am an amateur photographer moving from point and shoot to DSLR. Clicking is my hobby. I prefer travelling light in terms of no. of lenses to carry around.

In to all kinds of photography...however prefer landscape and outdoor clicking..

My budget is around $800-$900(all inclusive)

Confused between the D5100 and D3200

D5100 has raving reviews..tilt screen..has got a price drop…but is an year old..

D3200 is newly launched…comes with an 18-105 kit..has guide mode for beginners like me..with wi-fi options and relatively feature rich..

Both look within my budget..i am looking at 1 lense (like the 18-105) to begin with and later add to my collection.

At this point i am still to understand a lot about photography and other minute details.

Request your views on the camera i should buy...i wont be changing the body for next 4 years atleast..

D3200 or D5100 or something else...??

Would be thankful if you could give a few reasons to your recommendation as well..

Thank you in anticipation.
