Getting an SLR isn't going to make you a master at photography!
No offence, but I know where you're coming from. To be a great photographer, you simply need to have an excellent eye for detail. And if you do have that eye for detail, believe me any damn camera will do. I'm seen photoblogs on the net of the most brilliant photos ever taken, and the guy uses a polaroid camera. I'd still call him a master of his work.
My sister's a photographer for the Hindustan Times, and I'm a technology journalist so between the two of us, I've had all the time in the world to experiment with all sorts of digital cameras including the high-end 16MP EOS 1Ds Mark II. And the conclusion I've come to is that SLRs are a bother. Especially if you aren't making a career out of photography. Yep it's probably a stupid conclusion, but it works for me.
Anyhow, I don't want to impinge on your ideas regarding photography, but from what I've understood from my sister's rants, Nikons don't take too well to the Indian climate and apparently the Canons more ergonomic, with a sturdier hold. Besides, I've lost faith in Nikons too, man. I've had the sensor of an 800$ Coolpix 5700 die on me. It was quite tragic.
