I don't agree.
I have an Audya and had a Pa-800, and I think Christian would have an easier time with dedicated buttons than invisable layers.
As to reliability, some may have had problems with older units, but I have never had problem one.
I am lucky to have a good dealer in Frankiev, and he is always ready to help, although I know he still might have to involve the distributor.
Dnj is right about a bad rap. This was partly brought on by Ketron for being cash strapped and releasing too soon.
All of this being considered, I personally love my Audya and would buy another If stolen.
Bernie
