I loved my Audya. I may some day get the 61-note version. I had no problems at all with it.
I now have a Korg PA3X 61, and there are many things I love about it as well, particularly the layout and physical controls. It also lighter and easier to tote around.
However, my opinion would be that the Audya would be easier for a person without sight to handle.
The Korg would be o.k. after you spent a lot of time setting it up. You can't go wrong with either if you can get good dealer support.
