Memory Express has the Nikon D3300 on for $519.99. I have never owned a digital SLR before. When I used to shoot film I used the Canon AE1, so I'm old school. What attracted me to this was the 24.2 mega pixels. I think they also had a Canon on for $499 or so, but it was an 18.1 mega pixel unit.
Here is the D3300:

Anything I need to know? I don't want to spend any more than $520.
Thanks!
