Ian the styles from Casio are OK but not the quality of Yamaha or Korg styles. I find the modern pop and dance styles from Casio the best. Yes Casio still use only 2 variations.

Yes I have the PA3X for a week now and it's great. Sound quality is amazing and totally different then the PA500 Musikant I had before. The PA3X has 450 styles onboard plus I have all the styles from the Musikant so no short on styles here
