DSLR Advice. I want to buy a dslr, but don't know what model to get

I want to buy a dslr, but i don't know what model to get. I'm interested in a camera that will allow me to make HD surf/skate videos, as well as use it for photography. I only want to stick to nikon and canon and around 2000 dollars is my price limit.

Suggestions would be great?

I have a Nikon D3100. If you ever have questions with something on the camera, or how to do something, it gives you a guide mode with step-by-step instructions. It just came out a few months ago, and I believe it's around $700-$750.It's also on the smaller side, for a DSLR. I've been able to fit it right into my purse, unlike some other elephants of a camera. Here's the link: http://imaging.nikon.com/.../index.htm

Hope this helps!
