Nikon 200-400 users

Just wondering what experience people have had with the 200-400 VR.
Do you find you can handheld the lens for short periods, or is it simply too heavy and really needs support full time?
With the dollar currently strong I am looking at purchasing soon.
B&H have it for $4999 USD at the moment.
Wonder what my chances are of getting it through without the GST?
