A music store the state of Conn, has two USED Kn7000 for sale at 2695.00 USD plus freight and insurance to ship. This is about the street price of a new keyboard.
They seem to have been listed on Ebay for quite some time, if I am correctly assuming they are the same 2 keyboards.
There was a used KN7000 sold there last week for about 24 or 2500. http://search-desc.ebay.com/search/search.dll?MfcISAPICommand=GetResult&query=KN7000&cgiurl=http%3A%2F%2Fcgi.ebay.com%2Fws%2F&ht=1&from=R10&currdisp=2&itemtimedisp=1&st=2&SortPrope rty=MetaEndSort&srchdesc=y&BasicSearch=
