THere's nothing wrong with PA1000. It is a great keyboard, ton of features and very good sounds and styles.
It is the EXPECTATIONS and maybe the COMPARISON that give it a colour (not a red one...) of being disapointing. But that is always user's perception.
There really aren't bad keyboards anymore, in this regard.
