Price of the new lens is £1300 just looked on WHE I would be tempted to go for the 150-500 with OS as that is cheaper and since you are looking for additional length, I doubt if you will miss the 100mm at the lower end.

Some shots HERE on my Flickr taken with the new 50-500mm OS lens. I was lent it for a few days along with a 7D. Nothing special as I was testing the handling of the camera more than anything but the stabilization seems to work quite well.
IMO IQ wise, the lens is no better than my older Pentax version.
