Hi everyone

,
My brother is going on a trip overseas and was wondering if there was a descent DSLR for imaging as I recomended a DSLR after hearing all the positive things that have been said on iceinspace about DSLR's.
The camera will be mainly used for scenic landscape shots.My brother would like a camera with a wide FOV and an ability to possibly make panoramic shots.
I did some research and found the Nikon D3100 DSLR which seems ok although its $600.
Also what is the difference from a single lens kit to a twin lens kit?
Thanks in advance
regards Orestis
