Please i need to know cos someone I know is selling their XP60 for $550 and I may be interested...How does the XP 60 compare to the Fantom ?? And what makes it better than the XP 30 and XP 50..

Last question...What is the diff between XP 60 and XP 80. ??

I'm mostly into arranger keyboards which is why I dont know much about synths....
