This has been an interesting thread. I have never owned a Ketron keyboard but do own the SD2 unit which I like very much. That said, like Diki said, the keyboard simply costs to much and unless a friend has one you never find one in a store to try out. I too was at Don's jam when AJ showed off the very first Audya and like everyone else, I was impressed with it's sound. But, until Ketron comes up to customer support expectations they can keep them.
