First, I can't help it by laugh at the cartoon above from "What the Duck!" as I really face the same scenario often where I find something very interesting to capture and by the time I configure my camera... the subject I want to capture is gone 
Most of the latest camera's in the market now a days has over 20 preset modes to choose from making it so confusing sometimes. yet, those preset modes (when used appropriately) will give us the best results. given, we have enough time to fiddle around the settings before we miss a shot 
Very often I get asked about the best beginner camera that someone can start with before buying a full featured DSLR camera.
I have been following the latest news and updates on camera's for the past 2 years and I have complied the following list to aid you in your future camera purchase.
There are three types of cameras that you may start with depending on your requirements and budget. there are the Entry-level beginners DSLR, followed by Advanced Digital Camera's and finally Advanced Compact Camera's. mind you that I am not talking about the slim compact Point & Shot cameras as those are completely useless and can't be ever compared to the above three types.
I am going to divide this article into three parts and today I will speak about the Entry-level beginners DSLR category. This category of cameras is the best to start learning photography with given that you can afford to purchase the camera with extra lens or two and a flash unit in order to enjoy the full potential of DSLR photography.
From this category I highly recommend you to pick either the following latest two DSLR cameras;
- Canon EOS 500D click on the link to view images and read review
- Nikon D5000

At first glance, the Canon EOS 500D appears to trump the D5000 in a number of key specifications: the resolution is higher (15.1 Megapixels versus 12.3), the maximum sensitivity is higher (12800 ISO compared to 6400), tonal depth is greater (14 bits versus 12), the screen is bigger and more detailed (3in VGA vs 2.7in QVGA), the viewfinder slightly larger and the headline movie mode can capture 1080p video compared to 720p.
In its favor the D5000 has a fully-articulated screen which allows great compositional flexibility in Live View, it sports quicker continuous shooting (4fps vs 3.4fps), a slightly more sophisticated AF system (11-point versus 9-point), on-demand grid lines in the optical viewfinder, and an easier user interface for beginners. In terms of resolution, the 500D may have the advantage in numbers, but in our tests there was very little in it, and crucially, the D5000 boasted superior noise and detail at higher sensitivities. ~ Quoted from Cameralabs.com

I don't want to add to the wealth of information mentioned by various camera websites and reviewers. so I leave it to you to read my recommended review by Cameralabs.com
You may get confused on what camera to choose when both of them are identically priced and has almost the same features?! My advice is to hold both cameras while shopping and see which one feels good in your hand.
When you order one of those two cameras make sure to learn photography either by reading books or attending hands-on photography courses because if you simply use the automatic functions in your camera! you are simply wasting your money and you will never get outstanding results from your DSLR camera.
The only issue with this category of camera's is that they are heavy especially if you carry it with a tripod and a heavy zoom lens. So if you are bothered with its size and weight you can check out the other two camera categories which I will write about very soon!
