Articulating screen on the Nikon d3100?

I recently bought a Nikon D3100 as my first dslr and my friend told me that it had an articulating screen. It turns out it doesn't at least on mine. I called radioshack the other day and they said that the stores model had an articulating screen. Now my question is:
Is there a kit or something that i could buy to get an articulating screen on my d3100? Is there any way for me to at least get a work around for it? I need to be able to keep the camera low to the ground but able to see the screen while i'm standing.
Added (1). I actually after about 45 mins of searching i found this: http://www.coollcd.com/619ah-7-inch-tftlcd-vga-monitor-no-touchscreen-hdmi-new_p634.html
i will be using my d3100 in a fig rig and i could possibly mount this on it? Would that work?

There's no "fix" or kit for this. You'll have to try to negotiate with Radio Shack for a trade.

The D3100 does not have that screen if I recall correctly, but the D5100 does. Not there's no kit or way to change this so don't bother. This is why you should always do your research on the web, and confirm that anything you buy has the features that you want. I say return it.
The D5100 is more money, you have other options if you want the moving LCD screen.

Canon T3i, it's more expensive, so if you like Nikon, just go for the D5100

As far as I know, the D3100 doesn't have an articulating screen built-in. The one you found may work but I advise you to go back to the store and see what they have as it obviously works already if they are bold enough to display it.

If you want to buy a second screen, then first check the manual of your camera if it has a video output. I doubt that it has one (considering how limited its overall feature set is, even lacking support for infrared remote triggers), as far as i know it can only record video to its memory card.
So… Probably there's no way to add any kind of additional screen to it.
