Thatguy,
D90 is a great camera. Unfortunately, it may not be available new any more, and if it is, it still would be close to 50k, and I am not sure if mabhi wants to go to that price bracket. The kit lens (18-105) that comes with it, although having a plastic mount, is a very very good lens as well for a kit lens with good optics, resolution and build quality. I was very close to buying this camera, used it for a while, but it is heavier and bulkier than the Canon 550D I was comparing the D90 with, with very similar image quality and low light performance (actually the colour saturation is slightly better with the 550D in higher iso, see the comparison in cameralabs.com). My wife did not like the bigger size and heavier bulk of the D90, because she has much smaller hands and wanted to use this camera once in a while.
Arj,
The 550D low light performance is exactly the same as that of the 7D, the both having the same sensor. In fact the 550D may have a slight edge in low light according to many reviews and dxomark (just like the Nikon D5000 may be just a tad better than the D90, both having the same sensor again, but I suppose the slight differences occur because of memory management which is more robust in the more expensive cameras). When I said the 7D is faster than the 550D, I meant that the 7D can take more shots per second in the continuous shoot mode, so better for sports photography. Actually the 550D is not much of a camera when it comes to fast shoot (I mean shots per second, otherwise focuses very fast and negiigible lag elsewhere). But otherwise, I am very happy with it. I can literally shoot in near darkness.
G0bble,
I am not an expert, just an enthusiast. However, if you avoid the entry level D3100 and 1100D where many of the adjustments are menu driven (I know, I owned the D3000 for a while), the next level like the D5000, D5100, 550D, 600D will give you faster adjustments with a few dedicated buttons. You have to see for yourself which one suits you the best. Look at my first post in this thread, and see how usually I shoot with my 550D. I hardly miss a shot. At times, when I have a bit more time, I do also fully manual and experiment. It's actually quite easy with these mid-entry level DSLRs these days. Because of the excellent image quality of these, many professionals also keep these as a second camera. At least these are much lighter and obviously much easier to carry around for a whole day in trying circumstances for a pro.
