Nikon D3000, D3100, and D5000?

For Christmas my family bought me a Nikon D3000, I asked for a D5000, but my mom got me the D3000 since it was cheaper. It looks like a good camera too, but my mom gave me the choice to return it tomorrow to get the money back and buy a D5000 with the rest of my Christmas money. Should I spend $200 more to upgrade to the D5000? Or keep the D3000? I'm looking for good quality pictures, I think both models have great quality, but the D5000 is better.

Another option I have, is the return the D3000, and get a D3100. Which camera would be a better choice? The D3100 or the D5000?

D5000 is much better since it has HD-video recording! But if you're more into "taking pictures" D3000 is okay! Since D3000 has a quick instructional option on how to take good photographs the D3000 is cool yet it doesn't have a video recording mode to it. But if you're into taking Photos and videos the D5000 is totally okay!
