Bill, I am not convinced..Roland has sold more E80's than G70's...
Personally I know of seven people that own G70's...2 People that own E80's , and 2 that own E60's..
The E80's are marketed thru the Home Piano dealers, and may have a false impression of leading sales[if you are relying on dealers opinions]..
I am sure I would love the E80 if I owned one, but with a choice...I would pass on it for the G70..76 keys are that important..
