Hi John . Thats an excellent post. for me the question has never been about the number of keys. Its about what i can do creatively with the instrument i have. I play live but i am also a song writer and arranger . Getting to know my instrument inside out is more important to me than the next instrument or competitor. I am not a 'typical'arranger keyboard customer. But most are very loyal to the brand just as you so elequently describe.
