I called MUSIC123 and they are in fact Viscount Piano's. They don't have any in stock (surprise, surprise) but they are on Backorder with no delivery date and not guaranteed for Christmas delivery.

The Viscount website does not mention the Valdesta line or the GX5. But I did learn Viscount owns Oberheim which I didn't know! :-)

Keep digging, I'm sure we'll uncover the real truth here and hopefully a great deal as well!!!
