What is the difference between these DC's?

[Grant Morris]

What are the important differences between these? The only real difference I see is the 1 micron bag that comes with the 760 and the 760's induction motor which is probably quieter (if it actually is a different motor than the 850). How does the 760 justify the additional $90?
