..I learned the hard costly way myself..
I also think future buying habits will change also...
It has for me already. Gone are the days when I felt I had to buy the latest thing, that mentality stopped at owning the PA1X, it was then I realised that I already owned something far more than I needed and it contained everything, great sounds/styles features. Keyboards are not going to necessarily improve anything you already do unless the sound difference has astoundingly changed which it usually doesn't.
