some questions for u first:
1) haf u done ur own research n searched for reviews online about these cameras?
2) ever considered about other brands?
hmm i did abit of CSI n checked ur post history.
u had somewhat asked the same qns as before about upgrading ur system. rhino123 also gave u advice u to go for d90 or d7000. if u dunno the differences between each camera u listed, this shows that u didnt really read up on reviews online about these cameras
If you yourself cannot answer the questions others have asked, then keep shooting with your cellphone cam. You're not ready for a DSLR yet.
So, why did you shortlist those models? Other than the obvious 2 reasons: Budget below 1.2k and it says "Nikon" on the front. What are your dislikes/likes about those models and which features of each appeal to you?
