Which DSLR Camera we should buy?

As we went home with my girlfriend after we had a bit of shopping and buy fruits for her mom, we had tête-à-tête for while that talks about our plan to buy a digital SLR camera. I immediately search for possible DSLR cameras. After awhile, we found this Nikon d40x because it can be bought here in and at the same time it has reasonable based on our comparison with cameras available in the as of now. But my girlfriend still wants the Canon or Sony brand of DSLR camera. Which is the best?? Help us and give your opinions or suggestions. Thanks in advance!
