Perhaps it has not sunk in yet but some in fact a lot of people are quite happy with their Technics keyboards whatever model and they certainly don't want you telling them that they ought to be moving on.
Just because you have never been able to find a keyboard that can satisfy you hence the reason why your machines are either in your motor home or a warehouse or even both places at the same time if you can work that one out.
OK so you are in the market for a new machine probably not the first in the world but then most people would just do it without the need to brag about it.
