I've been quite happy with the lens. It was certainly worth the money IMO (which is not much!). It seems quite sharp for the price.
The VR gives me about 2 stops (when desperate I can handhold down to about 1/10th; combined with ISO 800 that gives me the ability to do a night shot when I forget my tripod).
The drawbacks I found are:
it is a little slow to focus, but if I set the camera to dynamic I can still reliably get sports shots.
On auto-focus you can't "tweak" the focus like you can with my 18-70
I would like a wider aperture, but it certainly fits in with anything else in that price range.
Here are some I've taken...
Best case scenario, good lighting and a stationary subject:
Sunning Koala
Worst case, night time action shot, requiring a high ISO
Goal Denied!
This is taken at 200mm on a tripod, but the photo has been cropped from its original 10mp size to an approx 1.5mp to give the impression of a macro. The spider was actually 1/2 way up a fairly large tree:

A couple more random ones...
