I have experienced the toy box scenario many times with my keyboards, most notably the KN7000. I never failed to come back to it without marveling at the sounds and ingenious OS. If the truth be known, from strictly a practical standpoint, I could have saved many thousands of dollars playing nothing but the Technics. OOH, how can I put a dollar value on the joy of the challenge and the thrill of learning something new on a new keyboard.

No regrets at all.
