The VR version sells for about that, the VR II version generally goes for $550-625, so it's not that bad.
it's a great all-purpose lens. Not the best at anything, but really very handy. It's on my camera 50% of the time.
(and if you can actually find a VR II for $400, please let me know where -> I'd love to swap out my first-gen VR)
I have checked ebay and you might get $500 for this lens minus ebay fees. It is better to buy new or used d7000. I myself thinking of buying just the camera from dell using amex $150 off promo.
