Tony, I'm afraid to disagree :) DSLRs produce image quality like nothing else. But yes, it doesn't matter WHAT you shoot with, it's HOW you shoot it !
Ara, I use an Olympus, got it for quite cheap 'cuz I was low on budget when I got mine (needed it for photography classes, I regret getting an Olympus sometimes). Anyway Canon is good if you want to go for it.
But Tony is right, you need to use Manual Mode to learn proper photography. If you're getting a DSLR in the first place just because you've heard that DSLRs produce good quality images, it's because the people who shoot those photos are trained to do so. You might rely on the AUTO mode for a while, but soon you'll realize that it isn't the way a DSLR is to be used. DSLRs are flexible, and you can manipulate the way your image looks and feels.
Have a look at this DSLR simulator. Get yourself familiar with the controls. It might look complex at once, don't worry.
