Nikon D40x vs newer model of dSLR?

I'm looking to venture into the dSLR world and was looking at Nikon. I'm a craigslist shopper and I came across this for 400$. Why should or shouldn't I take this deal?

I know this camera is older but since I'm new does it matter?

Added (1). If I should get new what should I get?

The d40x is an excellent camera, but truthfully, buying camera equipment used off of ebay is a huge risk. You don't know how many shutter accusations it has (the least of your worries), you don't know if the previous owner took care of their equipment, you don't know if the camera had been touched by water, if everything works, etc.

along with that, you don't get warranty.

My advice, get a new DSLR camera, something you know will work, with warranty.
