diki I wish they do make a 76 to your liking....I prefer a 61 but that is me ....what anyone else enjoys is not my concern...Yamaha, Ketron, Korg, Roland , I have played them all on stage.....all I care about is If I like it and it does what I need to make a living as a musician.
I am not defending anything.....good luck on your quest but right now I'd say stick with your G70 & make great music..
