Thanks....that's what I thought. I'm finding a few vendors, and not just at eBay, that aren't including the power supply with the keyboard. Yet, they are advertising these as brand new and fresh from the factory. They want an additional $75 for the supply!
Maybe this is how they make their prices so attractive. Why does Yamaha allow this? I noticed that in Yamaha's specs they do say the power supply is included. Let the buyer beware!
