Nowadays, with so many different models around, choosing a DSLR camera can often appear to be a complicated issue.
That being said, the one thing that you're probably going to have to do is narrow down your options according to your price range and see what you have left.
Mind you -- most DSLR cameras aren't cheap so if you have an extremely small budget you might find that your options are really severely limited.
Still, with a mid-sized price range, you'll find that you have many options to choose from.
One of the things that you'll need to decide initially is whether you just want a DSLR camera, or whether you want a package that includes lenses, and possibly a stand, to go with it.
If you've previously owned a camera you might not need these things (but you'd need to find a camera that is compatible with your old equipment).
Once you've decided if you want a full package or just a standalone camera, you'll be able to see what options are left to you.
Look at things such as the resolution of the camera, the sensor, the formats it is able to shoot in, and all the other usual suspects.
Also, be sure to find reviews of the camera if you can because they'll give you an unbiased perspective on what you'll eventually end up with.
It might even be worth checking out second hand cameras as well! End of the day, choosing a DSLR camera within a price range is mostly all about getting as much bang for your buck as possible.
In most price ranges, you'll find that there are certain models that appear to be a little bit better than the rest -- and these are the models that you should focus on.
Who knows, you might find a real deal.
