Nikon d60 with 18-55 lens for 285$ shipped?
Is it worth it?
It is an excellent price as long at the camera and lens are not damaged or missing the accessories that came with the camera.
Where are you seeing this? Normally anyone asking this little money for such a camera is running a scam and all they really want is your credit card number.
In most of these cases you'll place your order which will be followed by an email that the product is on back order. It will stay that way and you'll never see the product but you may see some unauthorized activity on your credit card or with your Identity. Be extremely careful.

Shipped? Meaning you didn't get the chance to examine the camera first before you paid for it? Just keep your fingers crossed then.
Otherwise, great deal!
