Yes, this is one of those "newbie asks for camera adice" types of threads.

For the last few weeks i've borrowed my ol' dads D90, with a 28-85mm(I think...) zoom and a Nikkor 60mm f/2.8 macro. While I don't have much to compare it to, I like the camera very much. As far as lensen go though, i've mostly just used the 60mm one.
Anyway, now it's about time I bought my own camera, so i'm looking for advice on a good camera and lense combo. The budget for this is as little as possible and asap. Meaning, I have very little money to spend on this and i'm not gonna sit around and wait for better times, when I can be out with camera in hand while there's still a lovely summer here.
This has led me towards the Nikon D3100. It's cheaper than a D90 and seems to have a slightly better sensor. The two major drawbacks i've found is that it can't use old AF lenses and there's no exposure bracketing. Other than that, it seems like the handling isn't as refined. Considering the price, including the 18-55mm lense, is about as much as a used D90 body it seems like a pretty darn good deal.
My primary interests are landscapes and cityscapes. I do appreciate if it's a little bit versatile, but I have zero interest in street photography or sports.
Now I mention the D3100 because it's cheap and seems to have alot of bang for the buck. However, I don't know much about the alternatives. That's why i'd like to know your thoughts on the matter. Any advice would be greatly appreciated.
