Coca, important 1st questions to help determine what kb is best for you are:

1) What was the reason you moved from Tyros to Korg PA1x?

2) If unhappy with the Tyros, cite specific things about it that you didn't like.

3) What are the things you liked about the PA1X over the Tyros, and vice versa?

4) What arranger keyboard features, sounds, and styles are most IMPORTANT to YOU?
