Help on identifying my new MacBook?

Hi everyone!

I recently got a MacBook for $500(Busted diskdrive but I got an external one). I got it yesterday. First off, do you guys think it was a good deal?

And I need help identifying my model. Please don't link me to a site. I think it is the 2008 model, but I'm not sure. THe webcam is a rounded square with two black holes on the sides. The touchpad has the clicker, so it's not all one big trackpad (which I love). Thanks!
