Don't limit yourself to a DSLR, if you are still experimenting with what you like to take photos of, then a bridge camera is a cheaper option. You still get the same features as a DSLR, but because you can't change the lens, and the sensor is smaller the quality is (arguably) not as good.
I keep badgering on like this because I have a bridge. It cost less than £200, and an equivalent DSLR set up would have cost probably £1k. But I can do all the things that a middle range DSLR can do (and some they can't). I do want a DSLR, and when funds allow I will treat myself. But I know that when I get one I will want certain things from it because of my experience with the bridge.
And as a bridge is cheaper, you get to start shooting sooner!
