I was thinking that although I prefer the casio because of its more solid feel. I should still get the yamaha because I have the fc3 pedal already, and the lighter keys would probably be better for my health.
And when the time comes for a real piano I would find one with a lightweight key action for the same reason
Thinking along the lines that The pianist tends to adjust to the instrument being played etc.
And in my case a lighter action would be appropriate due to my unique situation.
On the other hand the casio px130 wasn't that particularly heavy, it was comfortable but after some time may get tiring. However, the problem lies in the part for the stand and pedal .. Extra costs. Casio resale value in my country is next to nothing. Build quality may not be as high as yamaha..
I am concerned that the px150 action is even heavier than the px130
And I have no access to a px150 locally.
With the yamaha I can choose to sell after some years and upgrade to a roland perhaps, or not upgrade at all if I grow to like the ghs action.
Eitherway I'm upgrading from a unweighted keyboard with 32note polyphony. I doubt I would be unhappy with my decision.
Lots of factors to take into consideration and my head is spinning to make this decision.
