As the G70 is discontinued already, and getting very hard to find, but the E80 is still in production (but still hard to find!
) and a more advanced model, I'd shoot for the E80 if I were trying to sell them!
The G70 action is probably the only thing that might make a convincing point to those who have never stretched out on an arranger, but we already know what the majority of arranger users prefer!
Just don't let anyone lift any of these if they are in risk of a hernia!
