Hey Luis ,
Perhaps you can tell us how you buy keyboards in your country .
Do you just order items like keyboards sight unseen ?
Is there a store near you ?
Have you ever met the person you bought your keyboard from face to face ?
If I had a problem with my SD1 , I have a repair station that can fix most things within a few days (if a part doesn't need to be ordered) .
Can you fill us in a little ? Dan
