Hi Diki.

The G70 here in the UK is far cheaper than the E80 and these are still selling very well. With you mentioning that the E80 styles have been converted for the G70 (and they are very good because my neighbour has a G70), I agree totally with you above.
The benefit of 76 notes would be great and the G70 is also lighter, so you'd get a far better deal going for a G70, unless the few extra options in the E80 are really what you need.

I still like the G1000 piano rather than the new ones in these arrangers. That machine was just so classy when it came out and is a great buy if any come up 2nd hand.
