For me it has to have to sounds/voices of the pro workstations like the motifs and tritons on an arranger keyboard. Also, to me the keyboard has to look sleek and sexy, something between the look of the motif and tyros. For a dream keyboard like this, I would spend any kind of money to purchase one no matter how long it takes to get one! For example of my dream KB would be the look of the MotifES with combinations of voices from the ES and the korg triton. This is only in my opinon that would make me purchase a KB with whatever the cost is!
