I had 2 Nord instruments, one stage 88 and one electro 3. I changed 3 stages and then took my money back and bought a kawai MP8 and i change 2 electro 3, used it for 2 years and sold it...for me, the most overrated company out there, pricey and very bad construction and reliability...i had kawai and Kurzweil all my life so, i can understand the difference...
And many of my friends had problems, sold the Nords and never looked back...
