Just a thought, Adorama is selling AF-S 55-200 VR II version for $146. That is a real upgrade to your 55-200 non-vr and it is much smaller, lighter and sharper than the 70-300VR that was mentioned above. It is $200 off the regular price with free shipping.

The downsides? It is plastic, it is DX only, and it is not f/2.8.
