People bidding on Ebay for a Tyros 4 (http://www.ebay.com/itm/Yamaha-Tyros-4-NEU-/251193483399?pt=Keyboards_MIDI&hash=item3a7c4c6087) Please be aware of the bid for a Tyros 4 at a ridiuclous price. I tried contacting the seller who is refusing to give me detials about the keyboard. Simple questions and the seller became a threat. It's people like this that makes the world turn sour. Sad, but we'll keep smiling at them
