Everyone,
I have been selling dozens of 900's and 700's over the past several months. Only a few have had any problems and two of the 3 had loose connections and the one Don Mason got had a damaged box which I'm sure was jolted very hard by the shipping carrier which damaged internal components.
There have only been a handful of problems compared to the numbers that have been sold.
The major problem has been some disconnected connections which have easily been fixed. If you get a keyboard with a disconnected cable it's a simple fix but if you get it and it's not disconnected, you should expect years of trouble free use.
Let me say again that the models being sold in Canada are coming on the same boats and planes as the ones here in the USA and then transported to Canada.
Also, know that Yamaha will not leave anyone without a replacement if there might be something you can't fix easily either yourself or by a repair shop.
