I have a Yamaha DGX-500 digital piano (it's very nice, I love it) that I need to move home with me next week. I had to throw out the box because I had nowhere to store it. How should I pack it? I was thinking of wrapping it in that mover's cling wrap and then putting a layer of bubble-wrap around it, but I'm not sure how well that'd work. I don't have any boxes big enough to accommodate it, and it doesn't have a case. Your opinions?
